Summary Segmentation fault when running javascript

Reported 2007-09-07 00:29:45 PDT
I loaded my xhtml file into WebKit (QtLauncher). My xhtml the contains a lot of javascript code and input widgets. The file gets loaded (some errors reported). When I click some input fields and scroll the xhtml up-down a bit it crashes and says segmentation fault.

Created attachment 16213 [details] xhtml file containing javascript that crashes WebKit I suppose javascript in the xhtml file is guilty of crashing WebKit, I have tesed WebKit with variuos sites and html pages with javascripts and I never crshed WebKit since this xhtml file

I have added attachment that I assume causes the WebKit crash.

Bug not closed. Found error. It is in Troltech's class "QWebNetworkRequestPrivate" in file "WebKit/WebKit/qt/Api/qwebnetworkinterface.cpp". The error is in line 136 in method "QWebNetworkRequestPrivate::init(...)". The following code "DeprecatedString pd = resourceRequest->httpBody()->flattenToString().deprecatedString();" assumes that server backend always exists or always sends back something. If no server backend "httpBody()" method returns null, I added sanity check for null and code now work perfectly. I don't know it this bug is to be resolved since I have already reported it to Trolltech. The code is different (I found the same bug in Qt 4.4.0 tp1). They will correct their code and when their code is merged into WebKit the error should disappear. Rikardo

Holger ran into the same crash some time ago. Your fix is identical to what he came up with and correct :). We'll submit it to SVN soon.
