file isExecutable
Changed a call to gtk_rc_get_style to be checked and double checked because
gtk isn't working right. I can't get the new version to segfault on sign on,
with or without a ~/.gtkrc file. In committing the patch to use
gtk_rc_get_style, i failed to consider the fact that gtk often doesn't work
the way I would expect but instead works in ways I would describe as broken.
I humblely appologize for failing to sufficiently test that patch before
committing it and promise to try to do better in the future. Hopefully this
fixes things.
