Seems I have encountered an unusal bug.
I run i3 Window Manager and use SpaceFM as my file manager and when I clicked on a log file I created for i3 bug tracking, Geany is taking every time on this particular file, 10-15 seconds to load. This happens every time, it's the only file I've ever seen such an extreme amount of lag to open something.
These are my specs;
Slackware 14.1 x86_64
Nvida GTX660m - drivers 331.67
Geany 1.24.1 (compiled from source)
i3 version 4.7.2 (from next branch)
I'm attaching the file i3.log causing the problem.
