Description (last modified by pavelz)
Environment
Adblock Browser 1.2.1
https://rink.hockeyapp.net/manage/apps/185237/app_versions/42/crash_reasons/99666833
Remark for testers
The crash is a blind production report without known reproduction scenario. The fix was a best guess derived from the stacktrace. The crash is supposed to be happening under heavy load, possibly a combination of loading multiple heavy sites. Some requests then would start from a worker thread, not a designated thread, which made WebKit unhappy.

Done.
I attempted multiple site loading and refreshing whilst conducting this test. I was able to reproduce the crash by loading some content-heavy websites such as imgur.com, Reddit, MSN and yahoo and then also loading into nvidia.com. Upon refreshing some tabs and the trying to load a link (Country selection, news article) on the Nvidia page, I was presented with a crash. I reproduced this multiple times on the following devices (Attached are the logs):
ABP 1.3.0-qa (814)
iPhone 6 16GB - iOS 9.2
iPhone 5S 16GB - iOS 8.3

@Scheer thanks for the report. Unfortunately we don't see the crashes in our system. The first one was not sent "because the limit of 25 for 109_AdblockBrowser logs has been reached" - which you probably figured out and cleared for the next, there the limit is reported fine. But we didn't get the next either. Have you started the app once more and allowed crash report submission?

@pavelz - Yes, on all but one occasion I allowed the app to send the crash report. The one that did not get through was due to Test object becoming unresponsive. Let me know if there is more information you would like.

After getting the permissions, I allowed 'always' on the crash report and followed the report through to the following link in Hockey App - https://rink.hockeyapp.net/manage/apps/185237/app_versions/42/crash_reasons/109391600
I have also attached the raw data file.

@scheer i confirm the HA crash report being the same event as the attached raw text log. It also is a fresh event. However, both records claim that the device was iPad Air iOS 8.1.4 and HA adds that the app version was 1.2.1 (739). Do you have an idea how this strange difference from your testing environment described above could have happened? I have nothing against iPad Air, but testing version 1.2.1 makes no sense :) Furthermore the latest 1.3.0 build still does not work on iOS 8 due to #3655 so you could not test it anyway.

@pavelz - As discussed, the log was from another version, that dropped into the Crash dashboard on HA at the same time (a little before) and hence was the incorrect one. As we said, I will try this on a few more devices and then report back on the issue to see if I am truly able to reproduce it.
