Debugging kio slaves

Hi all,

Updated my Mandriva 2009.1 KDE 4.2.x to the 4.3.1 in kde.org and am seeing
problems with my ftp:// access not working. As I quite seldom visit ftp sites
this problem might even be from the last update from Mandriva 2009.0 to 2009.1
(KDE3 -> KDE4).

Keeps telling me that "The program that gives you access to the protocol
ftp://aaa.xxx.ccc died unexpectedly"

As this works fine downstairs in my self compiled environment I am sure it is a
configuration or "double library" problem. But my problem is finding out where
things go wrong as kio_ftp is not called directly and it seems to very hard to
intercept what is going on.

My questions are:
- Has anyone seem and solved a similar problem?
- Any hints on how to attack the problem.

In hope of good advice
Dag

Are you using a proxy -- any proxy, ftp or not?  If so, there's a bug in
4.3.1 (at least, don't know if it's in 4.3.2 or 4.3.0 or earlier).  I
don't have time to look up the bug number ATM, but basically, the error
says something about smb:// on one line instead of ftp://.  If you see
that and run a proxy (mine was an http-only proxy, not set for ftp at
all), it is indeed a kioslave issue, with a workaround of editing the
config file, $KDEDIR/share/config/kioslaverc or some such (going on
memory, and $KDEDIR will be ~/.kde or ~/.kde4 or some such depending on
distribution and local settings), commenting out or deleting the invalid
port-only (no IP address only port) ftp proxy settings there.

Thanks Duncan for this info.

I found the bug report you are referring to, but that was not my problem. The
real problem seems to be that ftp over a proxy is broken in the current KDE4
:-(
There are several bug reports on this and quite old ones too.

The reason everything worked "downstairs" was that that is the only machine
that is directly connected to the net, all others are proxied through that
one.

Best (and thanks)
Dag
