closing, coldcard plugin is not merged.

[SomberNight]

The coldcard plugin was merged quite some time ago; you must be thinking about #5440 which adds multisig functionality to it.

This issue is might be caused by a bug in existing functionality

Good morning @ecdsa,

I just received another crash report related to this issue. The crash occured on Electrum 3.3.8.
I'm not sure which versions of Electrum include the fix but this is the first report from anything
newer than 3.3.6 since you closed the issue.

Could you please check if this issue really is resolved? Here is the traceback that I just collected:
