[Bug 123273] kded often crashes on launch

[Robert Persson]

You have been subscribed to a public bug:

Often kded will crash as kde starts up. More often than not it will
relaunch, but sometimes I find that it hasn't relaunched. I typically
find this out when something won't print and I have to restart kded from
the command line.

Unfortunately the backtrace when it crashes claims to be useless. If you
could tell me how to furnish you with some more useful information I
would be grateful.

I am also the reporter of #120893 (kded hogs cpu), just in case these
two bugs are connected. I haven't experienced #120893 in quite while.
However this crash bug occurs quite a lot—perhaps 30%-40% of the time.

One oddity that might be worth mentioning is that when the trash applet
launches I usually (but not always) see a box with a progress bar pop
up, hang at 0% for a good while, and then disappear. No further icons or
applets appear in the panel until this box has closed. Nor will any
icons appear on the desktop until it has done so. The kded crash
notification appears after this progress bar has appeared and
disappeared.

The backtrace, for what it is worth, is as follows:

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.
