Summary0001971: Crash in AudioSpectrum when leaving Kdenlive open for some time
DescriptionThe audio spectrum is visible but "auto refresh" is turned off.
I open Kdenlive to do some quick tests not involving the spectrum and then switch back to Kdevelop often leaving Kdenlive running.
After some time it crashes.
TagsNo tags attached.
Build/Install MethodManual build from SVN

Strange. I have no idea how this can happen.

if (m_aTrackMouse->isChecked() && m_mouseWithinWidget && mouseX < m_innerScopeRect.width()-1) {

m_aTrackMouse should only be deleted when kdenlive is closed. So why should this trigger a segfault?

Are all audio scopes switched off (including the volume widget) or hidden?
How long is «some time» usually?

PS: I tried to reproduce it (with qtcreator). Even after waiting 10+ minutes I did not get this crash.
Wonder what it might be ...

All audio scopes are switched off. They are tabbed together with the audio spectrum so only this one is visible.
The height is very very small, much to small to be usable.
Mouse tracking is checked.
The time varies: I would say from 3 to 15 minutes.
I am just doing some tests...

Test somehow failed.
No instance of Kdenlive crashed (the day I reported this every instance crashed) however two processes remained open with 100% CPU usage although the windows were closed. Either an endless loop or a hidden benchmark to find out the best the playback settings ;)

Today it crashes all the time again.
Yesterday I opened Kdenlive, added a clip, moved it to the timeline, and then waited.
Today to test out a widget I am currently working on I add a clip, move it to the timeline, add a (video-)effect and play a bit with the widget. The main difference is that the frame gets updated very often in a short time because of me changing a parameter value very fast.

Should be fixed in r3517.
for (int i = 0; i < size; i++) with size < 0.

Did not crash again since then.
