[Qgis-developer] FW: QGIS sometimes freezes in Windows 7 x64

Mon Sep 22 04:16:44 PDT 2014

Hi Matthias.

I was a little too fast in my previous mail. The final lines from DebugView wasn't from QGIS but from my browser :|

Here I have the last lines DebugView received before QGIS stopped responding:

Hi Matthias.

I have tried DebugView and shortly after QGIS stopped responding. It gave me loads of information, much more than I will post here.

I can see a lot of invalid geometry exceptions regarding "Invalid number of points in linear ring": 

[10468] ..\..\..\..\..\src\core\qgsgeometry.cpp(99) : (throwGEOSException) GEOS exception: IllegalArgumentException: Invalid number of points in LinearRing found 3 - must be 0 or >= 4 [10468] ..\..\..\..\..\src\core\qgsmessagelog.cpp(45) : (QgsMessageLog::logMessage) 2014-09-22T11:12:46 GEOS[1] Exception: IllegalArgumentException: Invalid number of points in LinearRing found 3 - must be 0 or >= 4 [10468] ..\..\..\..\..\src\core\qgsgeometry.cpp(99) : (throwGEOSException) GEOS exception: Shell is not a LinearRing [10468] ..\..\..\..\..\src\core\qgsgeometry.cpp(99) : (throwGEOSException) GEOS exception: Unknown exception thrown [10468] ..\..\..\..\..\src\core\qgsmessagelog.cpp(45) : (QgsMessageLog::logMessage) 2014-09-22T11:12:46 GEOS[1] Exception: Unknown exception thrown

Some of these exceptions are also written to the QGIS message window (which I have open outside the QGIS window). 
I guess they comes from the geometry simplification used by QGIS to speed up rendering.

I have attached the final lines from DebugView[1] and I guess they are responsible for QGIS not responding.

Should I create an issue for this?

I'm not a windows user, but if I remember correctly you can get debug information with the tool debugview [1] (only on debug builds - that means 2.5/master but not 2.4). Maybe you get some interesting information there?

Thank you for taking the time to help resolve this problem.
