Description

Hi Electrum Team,

Thank you for an awesome Bitcoin wallet! Unfortunately, I'm now having some major issues with it.

Pressing tab in 4.5.4 results in a segmentation fault. Also, sending Bitcoin. No issues with 4.4.6. This is on FreeBSD using Wayland.

Output of setting up a new testnet wallet, then pressing tab on the main screen.

python3.9 -X dev -X tracemalloc /usr/local/bin/electrum -v --testnet 2>&1 | tee electrum.log

electrum.log

Thank you!

Research direction

Start by reviewing the supplied electrum.log and reproducing the failure with the documented Python command on FreeBSD using Wayland. Compare behavior between Electrum 4.5.4 and 4.4.6, including tab navigation and sending Bitcoin. Done means the reported segmentation faults no longer occur in the affected workflows.
