Comment 2 Jaromir Uhrik 2009-03-20 11:10:06 UTC 
It was probably caused by clicking on attachment before the progress bar finished.
Comment 3 Tomas Stupka 2009-03-20 17:48:00 UTC

BugzillaIssue.addAttachment() refreshes the issue several times. This results in several EVENT_ISSUE_DATA_CHANGED 
events. The IssuePanel attempted to refresh itself during these events. Hence, I guess that there could be some race 
condition that allowed IssuePanel to ask for comments at the time when they were partially refreshed (e.g. mylyn 
libraries returning null for comment creation time).

I have modified the IssuePanel (changeset 5f8b60787b5c) to avoid refreshing when the issue (including attachments) 
changes are submitted. Therefore I believe that the mentioned race condition should be avoided by now. Hence, I suggest 
to close this issue as fixed.
Comment 5 Tomas Stupka 2009-03-23 16:28:08 UTC 
ok then, fixed
