I suspect this to be another crash caused by running out of file descriptors, since it looks like it is happening when initialising a new socket descriptor. In which case it should be fixed by 630939e388beb4eaf6387a4f9bb827a87fdd0478

Can someone confirm it is fixed by that? Should be easy when 10.1 is released

Doesn't seem like it has gotten fixed. Plus, I think each process has a max file descriptor limit. We were overflowing the process's max limit. Not the global one. I think.

Simeon, should this also be fixed with your "Fix QTBUG-18934 by checking return value of qt_safe_pipe " Qt commit? 
(asking as a packager, as i did not experience the bug)

Unlikely - I thought about this a bit more, and I suspect it is because the storage service is receiving an X error at an inconvenient time, which causes an uncontrolled shutdown of qapplication, starts to kill some singleton classes and then new socket opens crash. 

But not sure why the X error is being received on startup. This only seems to happen on opensuse and ubuntu, so is it perhaps an apparmor thing?

Ok ;-) I asked as that commit was added to our Qt package, but a bit too late for inclusion in 12.3, so i was wondering should we issue an update for it.

Well, we have it disabled by default on openSUSE (and tbh i am not sure our apparmor packages are in usable state), so i doubt it's that.

Yup, probably not worth it

Aha, thanks. That rules out one more hypothesis.

Ok - so my present guess is that the X error being received is "X server not yet ready". 
If so, we can fix this by just starting nepomuk a bit later (with the added bonus that kde will start a little faster because it won't wait for nepomuk). 

If my guess is right, the bug can be fixed by executing at a terminal the following command (for OpenSuSe):

sudo sed -i -e "s/X-KDE-autostart-phase=1/X-KDE-autostart-phase=2/" /usr/share/autostart/nepomukserver.desktop

Can someone who can reproduce this try that and reboot a couple times?

Thanks

> I suspect it is because the storage service is receiving an X error at an inconvenient time

No, the XIO Error is because of the crash in thread 4 (original report).

Simeon, actually I didn't saw anymore crashes with 4.10.3 
Your fix (starting nepomuk later) cause klauncher error in folder view I've on my desktop, one pointing to Desktop and another one for nepomuksearch:/

Christoph: Why do you say that? You are probably right because you have been doing this longer than I, but could you elaborate? How does a crash reliably cause an X error (it's in every backtrace there, I think)?

See for example discussion at bug 194750, or http://lists.kde.org/?l=kde-core-devel&m=124388224108162&w=2

I guess when a thread crashes, the connection (pipe) to the X server is closed, causing any subsequent X calls (from other still running threads) to generate an XIO error. For details, you would have to ask someone more familiar with X internals, such as Luboš Luňák.

Ah - I see. Thank you. Then I guess the problem is some sort of race on startup, probably causing a double deletion (since it is a pure virtual crash). My hint helps just because it changes the startup order enough to avoid the race.
