First, enable WPA key decryption: in Edit > Preferences > Protocoles > IEEE 802.11 > Enable decryption and add a decryption key
In the same dialog, click Edit... then add a new wpa pre-shared key (or a wpa password). Go to https://www.wireshark.org/tools/wpa-psk.html to generate you pre-shared key from password if needed
Then, start capturing on a monitor mode enabled interface to capture WPA wifi packet. As soon the capture start and that WPA crypted packet are captured, wireshark crashes with a sefgault.
Here is a backtrace
