Summary

0001075: crash when kdenlive_render is not in $PATH

Description

i'm copying this directly from freebsd.org: http://www.freebsd.org/cgi/query-pr.cgi?pr=136882 [^]
obviously this is NOT limited to ${KDE4_PREFIX}, which is specific to freebsd

when trying to render the project from GUI, script execution crashes. it happens when $PATH is not containing kde4 bin directory ( /usr/local/kde4/bin ), so the script cannot find kdenlive_render.

Steps To Reproduce

try to render some kdenlive project in GUI without having ${KDE4_PREFIX}/bin in $PATH environment variable.

Additional Information

i guess no linux user is going to face this problem, but it would be nice to find a fix for it. not really important anyway, at the moment we patch it in the ports system

the interested code (then jb is aware of the problem described below):
QString renderer = QCoreApplication::applicationDirPath() + QString("/kdenlive_render");
if (!QFile::exists(renderer)) renderer = "kdenlive_render";

from http://doc.trolltech.com/4.5/qcoreapplication.html#applicationDirPath: [^]
Warning: On Linux, this function will try to get the path from the /proc file system. If that fails, it assumes that argv[0] contains the absolute file name of the executable. The function also assumes that the current directory has not been changed by the application.

conclusions:
it's quite difficult to find any linux user with /proc unmounted, that's why they're probably not going to suffer from this. also, i don't know if that statement applies to freebsd too. i can't reproduce this issue, since it works for me with /proc mounted and unmounted

(0003782) j-b-m (administrator) 2009-08-10 22:05	Could you test if latest svn revision (3813) fixes the issue ? thanks

(0003783) xzhayon (developer) 2009-08-10 22:17	weee i wasn't even asking for a fix, thanks! :) i won't be able to test this until 0.7.6 is out (and i make the port for it), but apparently it should be ok. anyway i can remember a situation where KStandardDirs() wasn't working as expected on freebsd, then we'll see i'll be back when i'll have some feedback
