Webview crash with google maps, QML bug or Webkit?

antpk

Hi all,

I would like some advise about an issue I'm experiencing. Under linux (ubuntu 12.04) using 5.0.1, I'm getting a crash using the example application in webkit, minibrowser.

If you navigate to "https://developers.google.com/maps/documentation/javascript/examples/":https://developers.google.com/maps/documentation/javascript/examples/ in the minibrowser app and zoom in and out, eventually the app crashes with a SegFault.

Here is the stack trace :

I tested it with the browser (widget version) and it worked all ok. Believe that uses webkit1 whereas the minibrowser uses webkit2.

I also tested it on a Mac and that worked all ok in the mini browser.

I have tried to get a git version of Qt working but haven't had much success yet.

I'm not sure if it's a qml bug, webkit bug or something related to linux? I was going to post a bug report on webkit but the more I think about it the less I can pin point where the problem is.

I would be grateful for some advice on what to do next?

Just an update.

Is there any magic to getting the debug version of webkit? Got Qt compiled with developer-build but can't get Webkit to work to try and debug. QML keeps saying it can't find webkit.

Any ideas?

Were you able to resolve this? We have a similar issue with Qt (5.x up to 5.3.2 currently) QWebView displaying Google Maps in a desktop app. Crash occurs on OS X and Windows, usually triggered by zooming.

Hi!

Have anyone been able to solve this? I have the same problem.

[0914/185750:ERROR:texture_manager.cc(1699)] [.RenderCompositor-004B7E70]GL ERROR :GL_INVALID_ENUM : glTexImage2D: <- error from previous GL command
[0914/185755:ERROR:gles2_cmd_decoder_autogen.h(1105)] [.Offscreen-MainThread-06242AA0]GL ERROR :GL_INVALID_ENUM : GetIntegerv: <- error from previous GL command
[0914/185755:FATAL:program_manager.cc(255)] Check failed: max_len == 0 || len < max_len.

the problem is only when I try to open google maps, but is exactly google maps that I want to use. When I try with a simple WebView, GoogleMaps runs in lite mode.

Thanks!
