I can debug, have a backtrace, and then I am not sure what it means.

Lars> what pointer?

I'll send as many gory details as I can, but not before next tuesday
unfortunately... In the meantime, look at the backtrace here:
http://marc.theaimsgroup.com/?l=lyx-devel&m=106640107014154&w=2

in frame #0, it seems that it is the 'this' which is wrong. frame #1
corresponds to the code below, where I highlighted line 265 with
<======. So a guess is that rdbuf() does not return a sane value.

Hope this helps.
