I noticed that on one of my systems, trying to use the sftp kioslave within dolphin (or from the command line) will fail with a dialog "Error. Out of memory" (Using KDE 4.4.4). It seems this has been fixed upstream in libssh. I upgraded to libssh-0.4.4 and the issue was fixed for me. Please see the following:
But this bug is already fixed by in-tree version. And we plan to stabilise that libssh with kde-4.4.4 so i don't see any problem.
Closing as fixed. Or please specify what do you want from us and reopen if this answer is not enough for you.
Nope, that's perfect if 0.4.4 will be stabled with kde 4.4.4. I just didn't find anything in b.g.o about stabling (and it isn't in the kde-4.4 keywords file) so I wanted to make sure it was known. Thanks!
