Bug 602820

Created attachment 423029 [details]
File: backtrace

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.

This looks like a gtk2 problem from the backtrace:

" thousands of file manager windows open up"

seems to rather indicate some kind of nautilus problem or operator error.

GTK+ can't really do anything against getting an X error if you open up thousands of windows.

That seems to be some sort of error path.  *I* am not opening up thousands of windows.  Something is crashing on the desktop and thousands of windows open up as a result.

This is a stop-ship as far as I'm concerned.  The system is completely unusable.

Raising Severity and Priority to match system crash level.

P.

The X error captured in the stacktrace is just a side-effect of the opening of too many windows. We need to figure out what causes nautilus to crash in a loop for you, if that is what is happening.

This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **

Moving to nautilus, which is the application that is crashing in a loop here. There is no indication that gtk is substantially involved here, apart from being the unlucky library that ends up on top of the stacktrace, due to having an X error handler.

Prarit, can you give us some repro steps? How did you manage to get your system in this state?

Nautilus remembers open windows in some situation and is trying to restore them on startup. By trigerring some issue we might end up in recursion, adding one more window in every iteration.

I tend to think this comes from some extension, can you please try to disable/uninstall them one by one ending with a clean Nautilus? Does this happen with new user?

I wish I had a reproducer :( ... but I don't have one.  This occurs on my work desktop about once or twice a month.  I usually have to shut down X and restart it in order to recover.

Sure, I'll give that a shot -- but FYI, I'm using the *stock* RHEL6 install.  I am not adding any additional features.  Also, I'm the only user of the system (two accounts, root & prarit).

[Aside: I hate getting bug reports like this too ;).  There's not enough info in this BZ unfortunately....]

Is there anyone in *Westford* that I can grab the next time this happens so they can take a look?

Weird, this looks like it has something to do with hardware, e.g. plugged devices. But I can't imagine why nautilus segfaults in that case. When there's something wrong, a layer behind crashes, that is gvfs in this case.

Besides these abrt reports, are there any other segfaults in dmesg? Does it happen right after login or during work?

Try Matthias Clasen or Ray Strode, they might give you more clues based on immediate experience. This could be a session issue too.

Tomas,

Next time this happens I'll run downstairs and see if I can grab either of them to come up and take a look.

I'm going to move the priority of this BZ to "low".

P.

Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.
