0002189: Moving multiple clips/transitions goes wrong ("Error removing clip at ...)

Notes
(0006947) j-b-m (administrator) 2011-06-25 22:19	I changed the handling of placeholder clips in svn rev. 5729, it should fix the problem, please test

(0006950) igloo (reporter) 2011-06-25 22:32	Does the change only affect placeholder clips? My real problem is with real clips, but my testcase uses placeholder clips as I don't want to upload several gigabytes of video :-)

(0006951) j-b-m (administrator) 2011-06-25 22:40	Oh, ok. I fixed a problem related to missing / placeholder clips. I did not understand the problem happend with real clips. That is a bigger problem. I see that your project uses proxy, that might be a proxy issue. Could you try to disable proxies and tell me if the problem is still here?

(0006952) igloo (reporter) 2011-06-25 23:00	If I turn off proxies in the testcase, with the placeholders, then I can still reproduce it. Incidentally, my ~/kdenlive/ doesn't have proxies for the clips anyway, so I don't think that can be relevant. I just tried to turn proxy off in the real project, but ran into this: http://kdenlive.org/mantis/view.php?id=2194 [^]

(0006953) igloo (reporter) 2011-06-26 00:51	Just to clarify my last comment: The real project does have proxies of the clips, but its project folder isn't ~/kdenlive/.

(0006962) j-b-m (administrator) 2011-06-27 09:54	Could you please test again with latest svn (both in real project and with placeholders)? I made several changes to the handling of proxies that should prevent crashes...

(0006964) igloo (reporter) 2011-06-27 13:19	With r5734, and the testcase in this ticket: After "Use placeholders for missing clips" the proxies stay as crosses rather than ticks. I continue anyway, but kdenlive seems to freeze at "Loading project 75%". $ strace -p 13356 Process 13356 attached - interrupt to quit futex(0x2297f8c, FUTEX_WAIT_PRIVATE, 1, NULL

(0006965) j-b-m (administrator) 2011-06-27 13:29	Thanks. The freeze shoud be fixed in svn 5736

(0006966) igloo (reporter) 2011-06-27 13:40	With 5736, moving things around in the testcase now seems to be OK. However, kdenlive is crashing a lot more. When trying to zoom out with the mouse wheel in the real project, I got a crash twice in a row: Application: Kdenlive (kdenlive), signal: Segmentation fault [Current thread is 1 (Thread 0x7fac66127780 (LWP 14538))] Thread 2 (Thread 0x7fac35a29700 (LWP 14542)): #0 0x00007fac63b7463b in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #1 0x00007fac651f061e in QWaitCondition::wait(QMutex, unsigned long) () from /usr/lib/libQtCore.so.4 0000002 0x00007fac651e4d6f in ??

(0007027) j-b-m (administrator) 2011-07-05 13:15	There was an issue with the "Do not validate clips on project opening" option that is in Kdenlive's settings dialog -> Misc. If that option was enabled, it caused crashes. I now disabled it so could you please test latest svn?

(0007054) igloo (reporter) 2011-07-07 02:53	I think you can close this.
