-- Information about the crash:<br>
- What I was doing when the application crashed:<br>
<br>
I've couple of opened tabs, one or two of which got an active search window<br>
with some simple criteria entered (i.e. only a numbers). After switching from<br>
one tab to another the whole application has crashed. Unfortunatelly I couldn't<br>
really remember if the target had search box opened or not. This is the second<br>
time issue is occuring in period of 24 hours. I didn't however managed to<br>
report it first time but the conditions tends to be similar - couple of opened<br>
tabs, one or two of which got something entered to search for.<br>
<br>
The crash can be reproduced sometimes.<br>
<br>
