New issue 1076 by dalewis: Intermittent hang in middle of search in
2.0.0.3767
http://code.google.com/p/qsb-mac/issues/detail?id=1076

What steps will reproduce the problem?
1. Hotkey to launch QSB box
2. Begin typing a search term (like s-a-f-a for safari)
3. Beachball

What is the expected output? What do you see instead?
Typing should complete.

What version of the product are you using? On what operating system?
2.0.0.3767

Please provide any additional information below.
This is intermittent, but noticeable -- maybe 1 out of 10 or 20 times. It
has always been after 3 or 4 letters have been typed and the application
I'm pursuing is resolved, i just haven't hit return yet. I have pasted a
sample below.

Comment #2 on issue 1076 by chuck.b...@gmail.com: Intermittent hang in

middle of search in 2.0.0.3767
http://code.google.com/p/qsb-mac/issues/detail?id=1076

This has started happening quite frequently lately, in particular after the
second character typed. QSB will usually hang with the SBBoD and very
little CPU/RAM usage, though occasionally it will hang while spiking the
CPU usage to 120-150%. In both cases it requires a force quit.

Process sample attached.

System information:
15" MBP 2.66 GHz Core 2 Duo, 8GB 1067 RAM, Mac OS X 10.6.8 (version 1, the
pre-supplemental update version)

Let me know if there is any other information that might help!

Cheers,
-Chuck
