2011, Октомври 7 05:20:55 EEST<BR>> I hit a wall with my application so
I am looking for someone to help<BR>> everywhere I can.<BR>><BR>>
The short version: how can I get qt creator to debug my application on
the<BR>> device. Right now I get CRC mismatch warnings for all
libraries and I assume<BR>> this is what prevents me to see any trace
information<BR>><BR>> That is what I get when I start to
debug:<BR>> ...<BR>> the debug information found in<BR>>
"c:/qtsdk/madde/sysroots/harmattan-nokia-meego-arm-sysroot-1134-slim/usr/lib/libpvrPVR2D_DRI2WSEGL_r125.so"<BR>>
does not match<BR>>
"c:/qtsdk/madde/sysroots/harmattan-nokia-meego-arm-sysroot-1134-slim/usr/lib/libpvrPVR2D_DRI2WSEGL.so"<BR>>
(CRC mismatch).<BR>><BR>> the debug information found in<BR>>

(CRC mismatch).<BR>><BR>> ...<BR>><BR>> I assume I need to
install "debug symbols/versions" for the qt libraries on<BR>> the
device somehow. Am I right? How can I accomplish this?<BR>><BR>> The
long version:<BR>><BR>> My applications uses qml\webview and
everything works fine until I swipe out<BR>> of my application and then
later come back to it. With one click or two I<BR>> get a segfault.
This is all the information that I managed to get running<BR>> gdb on
the device:<BR>><BR>> (gdb) backtrace<BR>> #0 0x42068924 in
