Comment 1 Jens Petersen 2006-08-01 08:05:13 EDT
I haven't seen this.  Is it still happening with latest rawhide?
Comment 2 Lawrence Lim 2006-08-01 19:36:21 EDT
There were a couple of instance where after upgrading to rawhide scim completely
stop working. Not 100%, thus, a bit harder to reproduce. If you can give me a
couple of days, once Test2 is ready, I will be able to confirm for you.
Comment 3 Jens Petersen 2006-08-01 21:16:10 EDT
Perhaps it is related to upgrades of scim-bridge?
Can you try testing scim-bridge-0.2.{5,6} to 0.2.7 for example.
Comment 4 Jens Petersen 2006-08-25 04:17:20 EDT
Closing this for now since I haven't been able to reproduce it.
Please reopen if you see it again.
Comment 5 Lawrence Lim 2006-09-19 03:25:10 EDT
This bug is still around. :(
Comment 6 Lawrence Lim 2006-09-19 03:28:40 EDT
Created attachment 136610 [details]
new trace for the bug

Step to reproduce is the same. Apply some changes in the scim-setup and click
Comment 7 Jens Petersen 2006-09-19 03:50:56 EDT
I can't reproduce on x86_64 at least.
Comment 8 Lawrence Lim 2006-09-19 21:24:01 EDT
Package Info
Comment 9 Leon Ho 2006-09-25 04:43:11 EDT
How frenqent is this issue?
Comment 10 Jens Petersen 2006-09-25 04:54:30 EDT
Lawrence, did you have a chance to test on x86_64?  Or should I test on i386?
Comment 12 Jens Petersen 2006-09-26 00:08:38 EDT
Ok, I have seen how to reproduce this now.

But looking at the SocketImpl::write method implementation in scim_socket.cpp
suggests this is probably the intended behaviour.
