SUMMARY STEPS TO REPRODUCE 1. Compile PyFalkon with Shiboken2 **configured by default, but instructed to use Python3** as follows: # for Shiboken2: $ pkg-config --libs shiboken2 -lshiboken2-python2.7.x86_64-linux-gnu #for Falkon $ pkg-config --cflags shiboken2 -I/usr/include/python2.7 -I/usr/include/shiboken2/ $ mkdir build && cd build && cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_VERBOSE_MAKEFILE:BOOL=OFF -DBUILD_TESTING:BOOL=OFF -DENABLE_PYTHON_PLUGINS:BOOL=ON -DPYTHON_CONFIG_SUFFIX=.cpython-36m-x86_64-linux-gnu # without the last thing it confuses Falkon not to compile (have a brief look also at Bug 409495, which is obsoleted by the present report) 2. Try to enable RunActions 3. Falkon crashes under gdb with a backtrace EXPECTED RESULT RunActions enabled SOFTWARE/OS VERSIONS Linux/KDE Plasma: Ubuntu 18.04.2 (available in About System) KDE Plasma Version: N/A (irrelevant, but) (Unity) KDE Frameworks Version: (irrelevant, but) any from v5.44.0 backported to, to v5.58.0 (backported) Qt Version: (less relevant, but) v5.9.5 backported to, or any released up to date ADDITIONAL INFORMATION reverted commits for real compatibility with Qt 5.9.5 and PySide2 << 5.12 479933e095168d07a54913f88642cfed4828c167 (fixed to use with Python3::Python) f792104be55fca03ad17cdc4244aafce47d0914e
