Muine crashes shortly after startup

[Crispin Flowerday]

Using dapper, muine crashes shortly after startup, running from the commandline shows no output on the console, and running it through gdb shows a pretty useless backtrace.

Is there any good way of debugging where the thing is crashing ?

I tracked this down to http://bugzilla.ximian.com/show_bug.cgi?id=76966

Are you still having this problem Crispin?

[Crispin Flowerday (crispin-flowerday-deactivatedaccount)]

No - I tracked down the upstream problem, no idea if it has made it into a mono release yet.

[Dean Sas (dsas)]

I've been able to reproduce this too, by importing the /dev folder into muine.

I don't think that it's likely there will be a new mono release before Dapper.

You can work around this by using gconf-editor to remove the offending folders from the muine watch list.

I've changed the affected product to be mono rather than muine as it seems this could be an issue in other programs trying to read from the /dev (or other) directories.

should be fixed now... please reopen when i'm wrong

[Dean Sas (dsas)]

Just upgraded to the latest and I still keep getting a seg fault on the same circumstances described above.

I've just reopened the bug.

[Sebastian Dröge (slomo)]

Sorry, my fault... it was committed to HEAD and not to the 1.1.13 branch.
I've uploaded a version with this patch now... 1.1.13.4-0ubuntu2. Please reopen this bug when the problem still exists

[Sebastian Dröge (slomo)]

this fix was broken... i removed it again and reported upstream

[Sebastian Dröge (slomo)]

ok, do you still have this problem? this should be fixed in 1.1.13.4 since some time...

[Dean Sas (dsas)]

I'm still getting the problem using mono 1.1.13.4 and muine 0.8.4.1ubuntu1

[Sebastian Dröge (slomo)]

Interesting... does the testcase from the ximian bugzilla fail for you?

[Dean Sas (dsas)]

The test case that you've posted works fine. './test.exe /dev'

I can't compile Crispins test case, I get the following errors:

dean@bells:~$ mcs crispin-mono-test
crispin-mono-test(3,7): error CS0234: The type or namespace name `Unix' does not exist in the namespace `Mono'. Are you missing an assembly reference?
crispin-mono-test(3,1): error CS0246: The type or namespace name `Mono.Unix' could not be found. Are you missing a using directive or an assembly reference?

[Sebastian Dröge (slomo)]

compile it with -r:Mono.Posix :)

[Dean Sas (dsas)]

Crispins testcase fails for me, I get stuck in an infinite loop with /dev/.static/dev/ataraid/d0 constantly repeating.

dean@bells:~$ ./crispin-mono-test.exe /dev

Unhandled Exception: System.UnauthorizedAccessException: Access to the path "/dev/socket" is denied.

[Sebastian Dröge (slomo)]

That's another bug... /dev/.static/dev/ataraid/d0 is no socket but a device... interesting...

[Sebastian Dröge (slomo)]

Filed upstream... http://bugzilla.ximian.com/show_bug.cgi?id=77759

[Sebastian Dröge (slomo)]

Should be really fixed now with mono 1.1.13.4-0ubuntu6
