[maemo-developers] N950 SEGFAULT - help?

[From: Ивайло Димитров]

 Why not install Qt debug symbols on the device and run/attach to your program there under gdb?

I hit a wall with my application so I am looking for someone to help everywhere I can.

The short version: how can I get qt creator to debug my application on the device. Right now I get CRC mismatch warnings for all libraries and I assume this is what prevents me to see any trace information

That is what I get when I start to debug:
 ...
the debug information found in "c:/qtsdk/madde/sysroots/harmattan-nokia-meego-arm-sysroot-1134-slim/usr/lib/libpvrPVR2D_DRI2WSEGL_r125.so" does not match "c:/qtsdk/madde/sysroots/harmattan-nokia-meego-arm-sysroot-1134-slim/usr/lib/libpvrPVR2D_DRI2WSEGL.so" (CRC mismatch).   the debug information found in "c:/qtsdk/madde/sysroots/harmattan-nokia-meego-arm-sysroot-1134-slim/usr/lib/libpvr2d_r125.so" does not match "c:/qtsdk/madde/sysroots/harmattan-nokia-meego-arm-sysroot-1134-slim/usr/lib/libpvr2d.so" (CRC mismatch).    ...
  I assume I need to install "debug symbols/versions" for the qt libraries on the device somehow. Am I right? How can I accomplish this?

The long version:

My applications uses qml\webview and everything works fine until I swipe out of my application and then later come back to it. With one click or two I get a segfault. This is all the information that I managed to get running gdb on the device:

(gdb) backtrace
#0
 0x42068924 in QPainter::save() () from /usr/lib/libQtGui.so.4
#1
 0x48ec294c in ?? () from /usr/lib/libQtWebKit.so.4
#2
 0x48ec294c in ?? () from /usr/lib/libQtWebKit.so.4

Program received signal SIGSEGV, Segmentation fault.

Any suggestions? 

Thanks in advance, 
Felipe
