Note this is not always happening, but very often. A visual evidence something is wrong is that you can not change the window icon with [wm iconphoto] it always displays a fallback image. I contacted the tcl irc channel and asked them for help. They told me there is a bug in Tk 8.5.8 that causes this behaviour and it has been fixed already.

Please include the mentioned path and update the ubuntu packages for 64bit!!!

Thank you very much

I just attached the core dump file

[saedelaere (saedelaere)]

I forgot to mention one more thing. I tried the latest activetcl release (8.5.8.2) - no more segfaults and changing the window icon works again. So the solution mentioned in the bug report here
https://sourceforge.net/tracker/index.php?func=detail&aid=3003353&group_id=12997&atid=112997
should work!
