I haven't noticed this in a long time, but that may be just because I'm
now aware of the possibility.  It was mostly the surprise that made me
report it as a bug.

But I just tried to recreate the bug in a virtual maching running sid,
by installing apache from sid and php5 from lenny and then try to upgrade:

And sure enough, the behaviour is still the same:

But dropping the unecessary "dist-" eliminates the problem:

Not sure if this really is a bug, or if it is to be expected.  Working
around it is certainly easy.  You just need to be aware of the
possibility.
