[KPhotoAlbum] current git master crashes ..

[Andreas Schleth]

Hi Tobias,

my actions in KPA:

1. rund demo mode
2. show thumbnails
3. doubleclick on any image
4. -

Here is my gdb session - after installing 167 debug packages still 
pretty useless (?):

as at wshome5:/home/usr/src/kphotoalbum-git/kphotoalbum/build> gdb

OK, I should build KPA with the appropriate cmake-parameter: 
-DCMAKE_BUILD_TYPE=RelWithDebInfo ..

Done that, run KPA within gdb and - bingo - does not crash!

run cmake .. & make again without parameters and ... no crash!

remove all C* c* files in the build directory, rinse and repeat: ... no 
crash!

So I added the 4th line (with the rm) to my build script (hey, I already 
had the debug info):

git pull
export CMAKE_BUILD_TYPE=RelWithDebInfo
cd build
rm -rf C* c*
cmake ..
make -j8
./kphotoalbum --demo

So, what do we learn here:
* Remove all remnants from previous cmake runs when doing a fresh build!
* And: *KPA does not crash if built properly*

This crash seems to have been the result of an inconsistent build 
directory (?)

Best regards, Andreas
