Yes.  Heaps of them, but they meant nothing to me.  (It's hard to give
a clue to the clueless!)

Apparently they meant something to Paul, who wrote:

Unfortunately I have no idea as to how to get the gdk-pixbuf on my
system to be the correct one.  I did a bit of a web search, but could
find nothing useful.  Can you give me some guidance?

For the record, here (again) are the error messages that are produced
when I try to start claws-mail from the command line:
