I confirm this bug in 7.7.8. With puzzle.png wipe transition. Even moving the cursor through this transition make kdenlive crash.
My OS is Arch Linux 2.6.36 64bit
Any pgm transition works fine in the same place

Using the imagemagick 'identify' command line utility, see if the PNG is 16-bit. There have been reports about crashing on 16-bit PNG because on some systems there is not a qimage or gdk-pixbuf loader for 16-bit PNG. That is why the build on newer MLT versions forces 8-bit luma generation when requesting PNG. The best solution is to request the packager to NOT use --luma-compress configure option for mlt.

Yes, I know the puzzle is not 16-bit, but I did not reproduce it with that PNG.
