Summary: kded4 crashes in kdelibs-4.2.1's kdirwatch module
(full backtrace present)
Product: kde
Version: unspecified
Platform: Gentoo Packages
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
AssignedTo: unassigned-bugs at kde.org
ReportedBy: k at 191a.net
Version: (using KDE 4.2.1)
Compiler: GCC 4.3.3 target: x86_64-pc-linux-gnu
OS: Linux
Installed from: Gentoo Packages
I had 1 konqueror window open, 1 konsole window open, 1 firefox window open and
the XFCE4 packages were being built in the konsole window using Gentoo's
package build system, Portage. Luckily, I have configured kde to build with
debug flags AND preserve debug information, so am able to paste the following
backtrace:
Application: KDE Daemon (kded4), signal SIGSEGV
0x00007f03a80bd901 in nanosleep () from /lib/libc.so.6

I'm also appending a portion of the emerge --info information. while much of
this is only of relevance to Gentoo, there are several pieces of information
that might be relevant to the bug fixers. Thanks for you guys' work on KDE,
it's awesome.
