Qt 4.8.7

Are you sure?
qBittorrent 4.x doesn't support Qt4!

Try to start with default settings (delete conf file). If it runs successfully try to change settings one by one to detect the setting that causes the crash.

i mean ... i've opened terminal, then pressed Qt then tab --> all i saw after that is qt4conf so i opened it and look after version. It was 4.8.7

BUT look at these lines or error:

/usr/lib/libQt5Core.so.5
/usr/lib/libQt5Network.so.5

I need an advice how to look up the Qt version through terminal. (command here, plz)

aint works. same crash every time, even after re-install.
after deleting a conf file the numbers of error lines is lower , but same crash and dump of memory
