Re: [PyKDE] Segmentation faults in pyqt
Hi, just for the record, so that when someone else encounters this: I found a cure for the problem. It appears that my font-handling was somehow corrupt - deactivating xfs and xfstt did do the trick for me. So its basically no PyQt problem, most probably not even a qt-problem but instead X11 multibyte gont related. I just wanted to post this here so it gets into the archives. Regrards, Diez B.

Re: [PyKDE] Segmentation faults in pyqt
> > libsip is SIP v3, not v4. Yes, I currently used the debian packages, which are sip 3.10.1 and pyqt 3.11 In the meantime, I created a debug-builds of python 2.3.4, sip 4 rc4 and pyqt 3.12 Still the same problem - so it appears to me that the problem is not something stale lying around.

I did that - I removed all things that appeared to be part of sip and pyqt,
and reinstalled the packages. Now all in /usr/lib/python2.3/site-packages is
from the same date (2004-05-21) and the libsip is from 2004-04-24.
Still the same behaviour :(

I attached the output - from what I understand, it looks ok.

Sure - I of course did that.

Thanks, but none so far :(

This smells fishy. I would start checking your system for old versions
of sip/PyQt, especially in /usr/lib/python. If this guess doesn't
match, send us the output of:
python -vc "import qt"

Note that changing sip always implies a PyQt (and dependants)
recompile.

[PyKDE] Segmentation faults in pyqt
Hi,
I've been struggling with this for a while now. I've got pyqt in various
versions running on two machines - as debian testing package, or self-built.
It works nice and smoothly.
But on the machine I care most about - the one sitting on my desk at home - it
segfaults - regardless of what I try: latest versions of sip, snapshots and
debian packages. Also no difference if I use python 2.2 instead of 2.3.
When stracing, the last thing I get from it is this:
lect(4, [3], NULL, NULL, NULL)= 1 (in [3])
read(3, "\1%\336\0\0\0\0\0\0\0\377\277\326\251\r\10\30\356C\10 "..., 32) = 32
writev(3, [{"1\0\v\0\1\0!\0", 8}, {"-*-*-medium-r-*-*-16-*-ISO8859-1"..., 33},
{"\0\0\0", 3}], 3) = 44
read(3, 0xbfffefd0, 32) = -1 EAGAIN (Resource temporarily
unavailable)
select(4, [3], NULL, NULL, NULL)= 1 (in [3])
read(3, "\1%\337\0\17\0\0\0\1\0\377\277\326\251\r\10\30\356C\10"..., 32) = 32
readv(3, [{":-ttf-andale mono-medium-r-norma"..., 60}, {"", 0}], 2) = 60
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
These are the various versions of sip/pyqt I tried:
sip-4.0rc3 sip-snapshot-20040329
sip-4.0rc4 sip-snapshot-20040501
PyQt-x11-gpl-3.12 PyQt-x11-gpl-snapshot-20040502
PyQt-x11-gpl-snapshot-20040413
I didn't try every possible cobination - usually one of the sip4 and after
that a snapshot. When 3.12 was released, I tried that. Building always went
fine.
The only app that doesn't segfault is tut2.py.
Any pointers to how to debug this are appreciated - if neccessary, I'll built
python, qt and sip/pyqt from scratch as debug versions, but I'd prefer to
have someone saying that that actually makes debugging possible before I
undetake that tedious task.
regardless from the trouble at home - where I got the chance to work with
pyqt, it surely rocks

Diez
