OT-1.2.0.2 AppImage Browser Crashes when using Icon mode on Linux Mint 18.1

[rwaguy]

Only happens on a certain subfolder in my Pictures directory. Posting here because the main OpenToonz GitHub doesn't produce a Linux version, and this seems that it may be OS-specific.

Used a simple strace, but it doesn't seem too helpful. 'strace -f ./OpenToonz-1.2.0.2-morevna-18.01.07-linux64-04bd8.appimage complains that it can't mount the AppImage.

Happy to run other tests, if they'll help. I'm not an adept programmer, but I'm vaguely familiar with a number of tools from gdb to radare2, and fairly knowledgeable about Linux, so I'll do whatever I can on my end to help resolve this issue.

I open the program, everything is fine until I open a folder in my "Pictures" directory. I ran it through the terminal, and after I clicked "Icon", OpenToonz crashed, and the following errors were printed:

Perhaps there's a problem with one of the images in that directory, but it seems that some sort of exception handling may be missing.
