GerbView is segfaulting sometimes. This happens about 50% of the time when first running gerbview from the commandline. If it successfully opens, then it is about a 50/50 chance that it segfaults when trying to open a file.
Here is the backtrace from clicking on a file-open button from the toolbar.
This happens on Linux debian, running in OpenGL. It does not happen when running in legacy or fallback.

Well this is almost certainly due to 14abe8723d but I can't figure out how to reproduce. I also run Linux (Ubuntu) and test a lot with OpenGL but can't see this crash. I'm not sure why it is particular to OpenGL as this is happening in the toolbar creation.
