Brendan,

sorry for the delay in answering, but I just spotted this mail today. More inline.

That is strange. My main datafile is encrypted ever since I developed the encryption support and I don't see this kind of problem her on my openSUSE system.

This reduces the problem to the encrypted path.

Ok, it tries to open the file for reading which fails. Since it uses a pointer to the object and works if it points to a regular (unencrypted) file, this leaves the conclusion that it has something to do with the KGPGFile object it points to.

The last change was in that area was to remove the virtual keyword from the KGPGFile::open() declaration. This should not be a problem, but one never knows.

Since you compile from source, can you apply the attached patch which will add the virtual keyword again and give some more trace output for those cases when KGPGFile::open() fails and report back?

Thanks in advance.
