Description

[Marcia Knous [:marcia]]

Seen while reviewing crash stats. http://tinyurl.com/4okdgj4 links to the over 28K crashes in one week. Sheila first noticed that there had been a significant uptake in crashes in this stack in Beta 10 and Sheila and I don't recall seeing this crash when we were looking at the B10 data (have not looked at it lately since we were looking at B11 and trunk). This crash also shows up in B11 with 324 crashes in the past week. There is a very small amount of crashes on the trunk.

The majority of the crashes are Windows 7 crashes.

chofmann's reports show this crash started showing up the 5th of February registering in the top 300 with 16 crashes. 

This is all Beta 10 day.
6th - not there
7th - there
8th - not there
9th - it appears as #2 with 2719 crashes
10th - 7,828 crashes

From that date on it was in the #1 spot on B10.

There were several fixes this area since b11 and the crash appears to have disappeared from b12pre (http://tinyurl.com/4zv73hk).

Ok, so maybe there was something there and it just got fixed. Not worth spending much time on then unless we see some similar spike. It was just odd that it kind of exploded after Beta10 had been out for a couple of weeks.

Closing because no crashes reported for 12 weeks.
