Someone else reported this problem, but so far I have not reproduced it on Ubuntu 10.04, Ubuntu 11.04, Fedora 14, and OS X. Both bug reports' backtrace show a crash in QVariantAnimation::registerInterpolator(), which I find strange esp. since our only Qt-based module, qimage, has not changed since before the v0.7.0 release. As you can see, it occurs when MLT calls dlcose() on a MLT plugin using Qt. Someone having the problem can easily see if deleting libmltqimage.so helps. I suggested this to the other reporter but have not heard back. > Output: > > me@gnu:~/Download$ gdb melt > GNU gdb (GDB) 7.2-debian > Copyright (C) 2010 Free Software Foundation, Inc. > License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> > This is free software: you are free to change and redistribute it. > There is NO WARRANTY, to the extent permitted by law.
