This regressed between 2007-07-18 and 2007-07-19.
So this regressed when bug 347736 was fixed (I get the plugin placeholder to see, with older builds).

Also crashes with Windows Media Player 11.

Still crashes with current trunk build.

[Johnny Stenback (:jst)]

Mats, any chance you could look into this for Beta2?

Comment 4

[Johnny Stenback (:jst)]

On second thought we won't block on this, but we really want this fixed. Does anyone have crash stats on this, how often do people run into this crash?

There is the npdsplay.dll crash on place 51 of the Firefox3.0.1 topcrashers list, but that's probably bug 136927, currently.

Comment 6

[chris hofmann]

the _SEH_prolog signature shows up frequently in possible malware attacks talked about in bug 591549

Comment 7

[Mats Palmgren (inactive)]

Works for me with:
Firefox 4.0 on Windows XP SP3, RealPlayer 12.0.1.609, WMP 11
Firefox 4.0 on Windows 7     , RealPlayer 12.0.1.633, WMP 12

[Wayne Mery (:wsmwk)]

Martijn, mats, 
does this still crash for you?  
(my system isn't set up for the plugin)

Comment 9

[Martijn Wargers (dead)]

Probably not, it's a very old bug.
