[KPhotoAlbum] current git master crashes ..

[Andreas Schleth]

Hi Hackers,

I just tried the current git master and it crashes in --demo mode if I
start a slide show (double click on any image in thumbnail view - also
when clicking the icon).

Version is: v5.2-22-gdf17f543

System: suse leap 42.2 with all current patches.

I can't reproduce this with current git master on Gentoo … could you post a
backtrace?

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 (?):

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
