[WebKit-devel] Flash plugin and webkitpart crash...

[Dawit A.]

As unbelievable as it may seem, if I use the default user agent string 
returned by QWebPage::userAgentForUrl, then I no longer get these crashes!! 
Dunno really know why yet and I do not feel like fishing into Qt's WebKit code 
to find out why... However after searching for the place the bt ends 
(XtRemoveTimeOut), it seems that neither the crash nor the possible solution 
are at all. As a matter of fact the nspluginviewer works around the issue by 
giving the nspluginviewer a fake user-agent string "Gecko" as well!!  See the 
refernce links below.

Anyhow, I guess it is reasonable to assume that the QtWebKit performs similar 
workaround and fakes the user agent string, but only if the default user agent 
string is used ??? Dunno... but sounds logical enough. 

Here are some useful links on this issue for future reference:
