Comment 1 David King 2011-05-27 22:43:39 UTC

Is it possible to provide exact steps to reproduce the crash? I tried:

1. Start Vinagre
2. Click the ‘Connect’ button. Make sure that ‘VNC’ is the selected protocol in the connection dialog
3. Click the ‘Find’ button
4. Select a server in the service browser dialog
5. Click OK
6. Click ‘Connect’ in the connection dialog

and had no problems. The bug report seems to indicate that the problem occurs at step 6, is this correct?

Comment 2 Andrea Corbellini 2011-05-28 17:07:57 UTC

David, yes: the problem occurs at step 6. I'm now using Vinagre 3.0.1 and the problem is gone. I can't test with 2.30, so I don't know whether this bug persists. But just to be sure: have you checked using Vinagre 2 or 3?

Comment 3 David King 2011-05-28 20:55:01 UTC

Andrea, I have tested with both 2.30.3 and git master, and cannot reproduce in either case.

Comment 4 g11024342@trbvm.com 2011-05-30 13:28:34 UTC

I have 2.30.3-1ubuntu2 and I can reproduce it easily. On different systems.

Comment 5 Fabio Durán Verdugo 2011-07-19 18:56:26 UTC

I can't reproduce in 3.1.3 ubuntu oneiric (3.1.3-0ubuntu1)

Comment 6 Fabio Durán Verdugo 2011-09-03 05:00:54 UTC

any can reproduce in newer version of vinagre?

Comment 7 Akhil Laddha 2011-10-17 05:30:50 UTC

Please feel free to reopen this bug if the problem still occurs with a newer
version of vinagre 3.0.2 or 3.2.0.
