I haven't noticed any side effects.

Same results for "Update/Merge" and "Watch/Edit" pref pages.

I was able to reproduce on 2 different boxes: Windows and Linux.

Sorry if this is not the right component for this bug.
Comment 1 Prakash Rangaraj CLA 2010-06-14 12:11:14 EDT 
Reproducible on Mac as well. Assigning to Team. I guess the help scopes are not properly defined.
Comment 2 Tomasz Zarna CLA 2010-06-15 04:34:35 EDT 
I've just discovered it happens to all pref pages named "X/Y". So it's also valid for "Compare/Patch", "Install/Update", "Run/Debug" and others. This is not a Team limited issue. 

Shouldn't there be a general fix on Help side for all these cases?

Moving to Platform/UA for comment.
Comment 3 Chris Goldthorpe CLA 2010-06-15 12:40:09 EDT 
The problem also exists in Eclipse 3.5. If you perform a help search for any term which includes a '/' an error message is written to the log.
