Description Russ LeBar 2003-03-05 22:11:29 UTC

Version:            (using KDE KDE 3.1)
Installed from:    Compiled From Sources
Compiler:          gcc 3.2.1 
OS:          Solaris

FYI, MetaFrame for UNIX uses its own xserver (i.e. *not* XSun). FYI, Kpager crashes on startup with a similar error message.


From the console:

ASSERT: "qstrcmp( locale, "en_US" ) == 0" in kernel/qapplication_x11.cpp (1968)
QFont::setPointSize: Point size <= 0 (-1)
kdeui (KPixmapIO): WARNING: Could not get shared memory segment.
konsole: WARNING: KDE detected X Error: BadShmSeg (invalid shared segment parameter) \x80
  Major opcode:  \x81


I compiled without debugging so this probably will not help, but here's the backtrace anyway:

Comment 1 Karl Vogel 2003-03-06 17:21:50 UTC

I believe this is fixed in the CVS HEAD branch. This was caused by a bug in
kdelibs' KPixmapIO function not properly checking the shared memory function
returns.

see Bug #42441

Comment 2 Stephan Binner 2003-03-06 20:47:16 UTC

Was it backported to KDE_3_1_BRANCH or not?

Backport fix for #42441 .

Comment 4 Stephan Kulow 2003-03-10 20:54:16 UTC

with Lubos's fix it definitly shouldn't crash anymore and with my kpixmapio 
fixes in HEAD it shouldn't even give the error (but that's not backported 
as it's suboptimal - Lubos is promising a cleaner version in Qt)
