Well, I guess the "obvious" was mainly verifying that the file was
actually there :-)
The log files you mention didn't offer a clue about what was going on,
but another file did - pluginreg.dat in the profile directory. It
actually had
[INVALID]
/usr/lib64/IcedTeaPlugin.so:$
1385126043000:$
I then remove the file and restarted, and now everything is back on
track :-)
I now remember doing this for other plugins in the past, but I'd quite
forgotten that there even was such a file until I was reminded by a web
search...
Another question is why the plugin was considered "invalid" in the first
place, of course. Maybe I'll never find out...
