Koen Aers commented on JBIDE-3119:
----------------------------------

I have been investigating this issue, but I cannot isolate it nor track down the problem. It only happens on my Linux/GTK box, on my Mac there is no problem. Can anyone verify if it happens on a Windows machine?

I have tried to mimic the dialogs in a minimal plugin setting, but the problem does not appear. I suspect it is a weird interaction that only happens on Linux.
