I tried that before looking for another bugfix/workaround - as it was
written in one of the previousresponses to this bugreport that
reinstalling helps.
I did run $ sudo aptitude reinstall libblas3 libblas3gf
but that didn't help and this is the reason why I tried making symlink
by hand (which actually solved the problem at least for me). I will check
the other day in QEMU if I can find a sure way to trigger the bug.
It is [not so] funny that yesterday mnemosyne was running properly, but
today I had this bug.

Luckily I still had logs from today morning upgrade:
Setting up libatlas3-base (3.8.4-5) ...
update-alternatives: using /usr/lib/atlas-base/atlas/libblas.so.3 to
provide /usr/lib/libblas.so.3 (libblas.so.3) in auto mode.
update-alternatives: warning: skip creation of /usr/lib/libblas.so.3gf
because associated file /usr/lib/atlas-base/libblas.so.3 (of link
group libblas.so.3) doesn't exist.
update-alternatives: using /usr/lib/atlas-base/atlas/liblapack.so.3 to
provide /usr/lib/liblapack.so.3 (liblapack.so.3) in auto mode.
Setting up libatlas3gf-base (3.8.4-5) ...

Maybe this will help.

Have a nice day,
