From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.6) Gecko/20040518 Firefox/0.8 Description of problem: If you create an advanced search with a bad expression, then click clear, all the messages in the folder you are currently viewing will be hidden with no way of showing them short of restarting evolution. Version-Release number of selected component (if applicable): evolution-1.4.6-2 How reproducible: Always Steps to Reproduce: 1. Start evolution 2. Select a victim mailbox which has messages within it 3. Go to Search -> Advanced 4. Change Subject to Expression and enter "a" in the textbox to the right. 5. Click OK (an error dialog will appear). Click Close. 6. Go Search -> Clear Actual Results: All messages disappear Expected Results: All messages to be displayed (since we have just "cleared" the search) Additional info: The Advanced Search's Expression feature is completely inscrutable and seemingly undocumented. I wound out working out its syntax by adding other rules and analysing the error message.
I just tried to reproduce this in evolution-2.0.0; steps 1-6 work as reported (with an inscrutable error dialog), but at no point do the messages disappear. So the permanent message loss part of the bug looks fixed in Rawhide; the rest I'm unlikely to spend engineering time on right now; resolving as fixed in RAWHIDE.
