Marco, after receiving your email the other day about this I attempted
to make it work. The approach I took was to create a PyQGIS plugin
which starts and stops an Eric4 python DebugClient [1], connecting to
the passive debug server in Eric4. It can connect and disconnect from
the server.

It catches exceptions [2]. However, I can't figure out how to set
breakpoints, step through code, etc. Sometimes, when clicking Continue
or Stop in Debug menu, after caught exception, QGIS crashes.

Any ideas Detlev, or Marco?
