Bug#403681: kpilot: KPilot no longer works with Handspring Visor
Package: kpilot
Version: 4:3.5.5.dfsg.1-2
Severity: important
I use KPilot with a Handspring Visor. Everything works fine with Debian
sarge.
With Debian etch KPilot does not work anymore. The assistant fails to detect
the PDA. After manually inserting /dev/ttyUSB1 as device and starting
the syncronization the Visor instantly gives an error message about a
failed connection and kpilotDaemon uses all the CPU.
The interesting part is that synchronization with jpilot actually works
under Debian etch (but this is not what I want).
I did a fairly long debugging session with one of the KPilot authors. At
first it was very difficult to get a useful backtrace because gdb in
Debian etch is horribly broken (but this is another story). Result of
this debugging session was that the error is not within KPilot but
somewhere else in the system.
I did test some other distributions regarding this problem. Here are the
results:
Fedora 6 - works
Suse 10.1 - works
Suse 10.2 - BROKEN!
Debian sarge - works
Debian etch - BROKEN!
There seem to be some changes in current Linux releases that are
breaking KPilot.
I did a fresh install of Debian etch (and downgraded gdb to v6.3) and
generated a backtrace (gdb kpilotDaemon, run --nofork, hotsync button,
crash, Ctrl+C, bt):
