I have repulled libs-gui from git and the problem is gone. My

10000004.000000. We correct this ...
workaround is no longer triggered.
Thanks a lot for your effort!!

According to my google search result forwarded a couple of days ago this issue
indeed popped up for others as well. One app that apparently triggered it was
ProjectCenter. I have never looked into the ProjectCenter code. But the problem
must have occurred in all apps that do auto resizing of the interface using
[NSControl sizeToFit] and have image only buttons (obviously a rather seldom
combination). :-)
Best wishes,
Andreas
