Ok, within a few minutes and without ever switching to any of the rcirc
buffers, I get
Setting rcirc-activity-string from [] to [#git].
Setting rcirc-activity-string from [#git] to [].

Setting rcirc-activity-string from [] to [#ema].
Setting rcirc-activity-string from [#ema] to [#git,#ema].
Setting rcirc-activity-string from [#git,#ema] to [].
The switches from [<something>] to [] should never have happened.
Hm, debugging a bit further, the problem is that `rcirc-activity' is
already wrong, i.e., it's oftentimes set to nil although there should
still be buffers with unseen activity. So then I tried to edebug
`rcirc-record-activity', and I got an error about a void-function
`pushnew'. I guess that edebugging interprets the function, so pushnew
is undefined because cl was only required at compile-time. Ok, now I
did (require 'cl)...
I also added a message in there plus a (debug) when rcirc-activity turns
nil, but of course since I've done that it's working properly for a much
too long time... Really strange. Is there any chance that the bug
occurs only in compiled code?

It's definititely not the first time where I could need something like
that. Maybe it could also be a bit more general, e.g., one could add a
watcher function to a symbol that's called whenever the symbol-value is
set.
