Errm, automatic bisecting doesn't work, b/c the issue can't be reproduced by a
simple "wget https://..."; - when I use konqueror - up to 6-10 times I'm asked
to confirm a cookie or something else before the crash occures.

And if I use "lynx -accept_all_cookies https://n22_uml/phpmyadmin/"; then I'm
able to login - so it has something to do with HTTP frames I suspected - but a
shutdown of the UML instance wasn't possible too after such a try - probably
something else then the HTTP frames itself triggers the issue ...

In short - it is not phpmyadmin (3.4.0) itself, but it triggers the bug (in
fact sometimes I even could see the login window within Firefox of the
phpmyadmin site before the crash happened).

Because therefore manual interaction is needed (or do you know an automated
way for konqueror/ff/.... ?) at least it would be helpful if the bisecting
could be narrowed doesn to a given path or somethign else.
