Hi Dr. Chapatin,

I can not reproduce it, could you compile it debug gdb:

cmake .. -DCMAKE_INSTALL_PREFIX=/usr    \
    -DKDE_INSTALL_LIBDIR=lib    \
    -DKDE_INSTALL_LIBEXECDIR=lib    \
    -DKDE_INSTALL_USE_QT_SYS_PATHS=ON   \
    -DK3B_BUILD_API_DOCS=ON \
    -DK3B_ENABLE_PERMISSION_HELPER=ON   \
    -DK3B_DEBUG=ON

then gdb build/src/k3b, please paste the bt info, thanks!

Regards,
Leslie Zhai
