Comment 1 Pavel Alexeev 2011-01-14 20:31:09 UTC
Hello. Firstlay thank you for the bugreport.

Please can you try new version from rawhide, is it fix problem or not?

Comment 2 Orion Poplawski 2011-01-18 17:38:55 UTC
Same error with x11vnc-0.9.12-15.fc15.i686

When it happened? How reproduce?

I run as you wrote, it seams runned. What next?

Comment 4 Orion Poplawski 2011-01-20 18:01:24 UTC
Looks like a race condition.  It looks like x11vnc forks and one process exits and on exit cleans up the icon_mode_file.  Works for me sometimes, but not others.

Comment 5 Pavel Alexeev 2011-01-20 20:37:35 UTC
Ohh, if it is not always reproducable it will hard to fix.
Can you try provide reproducable and conditions for that?

Comment 6 Orion Poplawski 2011-11-22 21:16:32 UTC
According to http://www.karlrunge.com/x11vnc/#beta-test this is fixed in 0.9.13:

Fix race condition in tkx11vnc gui where the comm file may be deleted before tail opens it.

I built it locally and it seems to work.  Don't seem to need x11vnc-0.9.8-XShm-explicit-include.patch anymore either.

Comment 7 Pavel Alexeev 2011-12-11 15:27:31 UTC
Thanks.
I hope it really fixed in this version.

Please check that build http://koji.fedoraproject.org/koji/taskinfo?taskID=3577890

Comment 8 Orion Poplawski 2011-12-14 22:42:17 UTC
Any chance of F16/F15 updates please?

Comment 9 Pavel Alexeev 2011-12-19 10:23:17 UTC
Could you please test it before? I think it should not have excessive dependencies. If it works I'll submit updates for the stable branches. Or you want scratch build for that?

Comment 10 Orion Poplawski 2011-12-20 22:35:00 UTC
tested it here and it works fine on F16.
