Strange Avast C++ Error is blocking internet connection

Avast Free Antivirus / Premium Security

A Error is blocking my internet connection:

"Debug Assertion Failed!
program AvastSvc.exe xtree Line: 293

Expression: map/set iberators incompatible

For information how your program can cause an assertion failure, see Visual C++ documentation on asserts.

(Press Retry to debug the application)

The screenshot can only uploaded in a few minutes because my ftp connection with freecommander failed - maybe also caused by avast.

Which version of avast do you have, exactly, and where did you download it from?

Thanks.

Thank you for watching my problem.

6.0.1289 Avast Internet Security
Downloaded form: files.avast.com/ and autoupdate.

The error is not on every website. Some websites with much advertisement cause this problem. In avast forum - no problem. But i dont know which website the problem caused because i use always alot of browser windows at same time.

Please, upload (attach) the avast log:
C:\ProgramData\AVAST Software\Avast\log\Setup.log
or C:\Program Files\Alwil Software\Avast5\Setup\setup.log

If the file is too big for the forum, post the last 400-500 lines of it.

Here the last lines of the setup.log

I guess its caused by ebay or maybe wetter24.de.
Now was the error message and ebay was active window in FF8 and wetter24 was in a inactive FF8 Window.
Btw, when i click on “Ignore” then the internet connection will stay. Only when using debug otion the internet connection will be blocked permanently.
Best regards

Edit: The Error Message come sometimes, no special internet site cause the problem, it happens on each website sometimes.
