[Bug 74653] konqueror hangs forever when opening pdf (nondeterministic)

[gsauthof]

Public bug reported:

Binary package hint: konqueror

Hi,

I am using kubuntu edgy edge (6.10). I observed that konqueror hangs
forever (no screen updates, no user input possible) when I click on a
pdf file.

Normally when I click on a pdf file, it is displayed inside konqueror
(via the kpdf kpart).

This issue is not deterministic reproducible. I.e. it is not observable
at every pdf file and it is hard to reproduce.

This time the konqueror process was runnung a long time (>10 days
including suspend-to-ram periods) and I have opened > 15 tabs).

An attached strace shows me only:
futex(0x85e39dc, FUTEX_WAIT, 2, NULL <unfinished ...>

I made a short and a full gdb backtrace (with -dbg packages installed).
I will try to attach the short backtrace log to this bug - if you need
the full backtrace, I can send it, too.

Also, I have a manually generated core file available - thus, I am able
to issue some gdb commands to it.

Best regards
