Crashes with: *** stack smashing detected ***: terminated on i686

[mtboehlke]

After upgrading zathura to 0.5.6, zathura fails to open any document, instead crashing with *** stack smashing detected ***: terminated Aborted For context, I am running Void Linux on i686 with zathura installed through the system package manager. It doesn't seem to matter which pdf plugin is used. I also tested opening djvu file with the same result.

I did have a chance to run a git bisect. The earliest problematic commit was 5447de8a4701aec496638486e02ebf6acae7bb45.

Here is the backtrace from gdb:

Let me know if there is any other info I can provide.

Thanks for the quick response! Sorry I didn't stop to think that this may be already fixed.
