[0.13.0, 0.13.1] Mod portal crash on Linux

[rhbvkleef]

When using the arrow keys to browse through the list of mods, or clicking on different mods, after a while, the game crashes and produces the following error message in the log:

http://pastebin.com/VymCA4Nk

Installing mods works fine.

Edit: Note: The log shows mods, but the issue is also occurring without mods.
