Summary

0002620: PNG clip file loading causes Kdenlive to crash

Description

I built an 849 x 6499 PNG file with alpha channel in Gimp (Vers. 6.2) to create a scrolling title in Kdenlive.

After restarting the Kdenlive(vers. 0.9, with KDE Development Platform 4.7.4 (4.7.4)) editor, I request that my project be loaded. I receive several warning messages that a font can not be found, and that it will be replaced with another font style. After acknowledging the warning, the program reports the project is loading, and shows a progress-"count down" bar. the progress bar stalls at 50% for a few monments. after the screen turns gray, the progression bar continues counting down to "0%" and the project comes up.

My first action, after the project comes up is to left click onto the "add clip" icon, and use the file retrieval interface to click on the png's file name. As I click on the 'load' button, the window vanishes, and less than a second later, the entire program interface window also closes, and the bug-tracker window opens. Each time the crash occurs, a new bug-tracker window is opened on top of the previous on, hiding it.

Steps To Reproduce

Application: kdenlive (0.9)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-19-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
<In detail, tell us what you were doing when the application crashed.>

The crash can be reproduced every time.

-- Backtrace:

Additional Information

This Kdenlive build was acquired from the ppa.launchpad.net/sunab/kdenlive-svn repository. The version that came with the Ubuntu upgrade to 11.10 oneiric was not loading successfully before I acquired this version.

The project consists of two video streams and audio tracks that were synchronized 'by hand' ( I am not familiar with all the program's features, yet). After syncing in the tracks, I have made more tracks available at the top of the stack to reduce the 1-3/4 hour-shoot down to an 1-hour show for Public Access TV. Titling graphics have been inserted on the top video track. I am learning, as I go, the peculiarities of this editor program. As I have progressed, there have been more crashes, as I've demanded scrolling animation of titles, using PNG files from Gimp(This has worked for me in the past, with Cinelrra).

Notes
(0008080) paskperfect (reporter) 2012-05-24 07:59	just upgraded to Ubuntu 12.4 (precise). I first tired running kdenlive, as upgraded by Precise: still crashes when I try to load the same PNG file. I then included the recommended ppa upgrade to leapfrog (in the repository section of Synaptic package manager). I upgraded then, to Kdenlive 0.9 (4.8.2). I find that the program still crashes when I attempt to load the PNG file. Hmm... Not all pgm files cause the system to crash. I wonder if size matters :-?

Crash in producer_pixbuf.c At first i blamed gtk libraries, so i recompiled mlt (last git version) with: ./configure --enable-gpl --disable-gtk2 Recompiled and crashed again in producer_qimage.c. I was really hurry, so i do this in src/modules/qimage/qimage_wrapper.cpp (line 236): ===================================================================== // QImage has two scaling modes - we'll toggle between them here // COMMENTED // if ( strcmp( interps, "tiles" ) == 0 // \|\| strcmp( interps, "hyper" ) == 0 // \|\| strcmp( interps, "bicubic" ) == 0 ) interp = 1; ===================================================================== So... interp ALWAYS be "1". Recompile (again with --disable-gtk2, i don't think the error is here) and then i can insert my 1440x12000px png image... but... thumbnail in Proyect tree is absolutly red... and preview monitor messed up (only with the png image)...
