Description Nomadic 2007-05-03 17:06:38 UTC
Version:           0.8.1 (using KDE KDE 3.5.6)
Installed from:    Unlisted Binary Package
Compiler:          gcc 4.1.2 ../gcc-4.1.2/configure --prefix=/usr --enable-shared --enable-languages=c,c++,objc --enable-threads=posix --enable-__cxa_atexit --disable-multilib --libdir=/usr/lib --libexecdir=/usr/lib --enable-clocale=gnu
OS:                Linux

connection: 
glftpd [TLS] ---FXP---> glftpd [TLS]

in transfered directory there is a catalogue [Complete] with permission denied (need only for display of the upload status) and being in the skiplist with skip when queuing

on start transfer kftpgrabber tries to make such:
CWD /dir
250 CWD command successful.
CWD /dir/[Complete]
550 - permission denied
CWD /dir/[Complete]/[Complete]
550 - permission denied
CWD /dir/[Complete]/[Complete]/[Complete]
550 - permission denied
CWD /dir/[Complete]/[Complete]/[Complete]/[Complete]
550 - permission denied
CWD /dir/[Complete]/[Complete]/[Complete]/[Complete]/[Complete]
550 - permission denied

etc...

By transfer on local side this dir - all ОК

P.S. Excuse for bad English...
