[fixed] Attempt to read or write protected memory for configuration items (1 Viewer)

[Smeulf]

New report tonight, but I think it's a pretty old bug.

While trying to change the configuration, or just display it, I have often (but randomely) this bug, and of course the screen to select the option is not displayed. I must add I can have 10 time the error until having (or not...) the menu shown.

[2011-08-18 03:23:34,794] [36802  ] [InputMgr ] [ERROR] - MethodDelegateCommand: Error executing method delegate
System.AccessViolationException: Tentative de lecture ou d'écriture de mémoire protégée. Cela indique souvent qu'une autre mémoire est endommagée.

Translation of the french message : Attempt to read or write protected memory. This often indicates that other memory is corrupt.

It ends up with this error too, see log (maybe it's 2 differents problem, we'll see) :

[2011-08-18 03:24:22,425] [84433  ] [AMQ 'ScreenManager'] [ERROR] - Unhandled exception in message handler of async message queue 'ScreenManager' when handling a message of type 'ShowDialog'

Step to reproduce : Settings / Players / Codec, try to show an option until the error comes (usually it shown after less than 10 attempts)

Can someone please confirm that bug ? Or is it my computer that have some memory problem ?
Cheers.

Smeulf.

AW: Attempt to read or write protected memory for configuration items

this is a COM exception, I will check the enumeration method if it does (not) free some items.

for reporting...

AW: Attempt to read or write protected memory for configuration items

I added exception handling to enumeration of filters. So I think it's fixed.

Please check it, if everything is ok: no exceptions, all filters available for selection...

It looks very good. Thanks. I set the bug to fix. I'll re-open it if I run again in the same situation, but I have the feeling it will be ok
