Problems with Mozilla 0.9.2

[Alejandro Alvarez Melcon]

I am having a lot of problems with Mozilla 0.9.2;
a bit surprised though, since 0.9.1 worked just fine.
Apparently the plugins do not work even if they are
copied into the plugins directory (for instance flash player
does not work in 0.9.2). Also the .wav plugin does not work,
and I get the following error message:

/home/amelcon/.mozilla/amelcon/l6f7xv3q.slt/NewCache/475ADE62d01: No
such file or directory

None of these happened in 0.9.1 which worked fine. Anyone can help?.
