Topic "TLS Bad record mac"

When uploading to a Filezilla server version 0.933 using SSL/TLS the upload fails with the server reporting:

Data connection SSL warning: SSL3 alert write: fatal: bad record mac
(This message comes from the filezilla log)

Research shows that this problem has occurred with clients that are compiled with older tls libraries (perhaps this is the problem).

Some additional info. I am using version 4.2.3(build 494) under Wine in Ubuntu Intrepid. I had the same problem with my previous version (I think it was 4.2.2). All other functions seem ok.

Here is an extract from the winscp log file at the point of failure:
