I have lodged the following bug report which contains a workaround to fix this problem pro tem:
passwordsafe 1.15 crashes on access to 'Edit Entry' after upgrade from Ubuntu mate 22.04.1 to Ubuntu Mate 22.10
I removed passwordsafe and passwordsafe-common from system using synaptic
then reinstalled passwordsafe-ubuntu22-1.15-amd64.deb using file downloaded from sourceforge
deb package installer warns me that a later version is available in software channel and strongly advises to install this version
I ignore this and proceed with the deb package installer
this reinstallation does not install passwordsafe-common
clicking 'Edit Entry' now allows me to view the entry
problem appears to be with passwordsafe-common 1.15
however, system wants to upgrade passwordsafe which installs the problematic passwordsafe-common
so I have placed a hold lock on passwordsafe for the time being
