Hm, Your backtrace looks like the one I just got for a similar problem.
Look for the subject hanging vim, I just posted there yesterday. Maybe
this is a problem with the Ubuntu X11 libraries?

In any case, starting vim with -X should also fix this for you.

I also saw Vim hang sometimes when selecting a large amount of text (see the

Vim crash issue I reported last week).

The traceback of the hung Vim is similar to the traceback you are seeing.

It looks like the X11 clipboard interaction has a problem. I am not familiar with

the X11 clipboard handling code. So I am not able to make any progress

in finding a fix for this crash/hang problem.
