not sure whether this is jobs or search...

- From within a plugin.xml
- press Ctrl+H to bring up the search dlg
- choose the file search tab
- enter "org.eclipse.ui.edit.text.contentAssist.proposals" in the search
expression (no quotes)
- enter "plugin.xml, *.java" into the filter field
- press search
-> got the exception in the log

Probably has to do with the filter expression...

This is actually a bug in JobInfo.getPercentDone.  If the task's total work is
zero, line 318 of JobInfo causes a divide by zero exception.  Since a total work
of zero is valid according to the API, this should be handled in JobInfo.

I haven't been able to replicate this but the section of code is pretty obvious.
Fixed in build >20050907
