Re: [Banshee-List] Segmentation fault

Hi Patrick,

Thanks for the advice.
I had a read through the Debugging stuff.....buts it is beginning to go 
a bit over my head ! Anyway, here is what I saw..

(gdb) run /my/path/lib/banshee/banshee.exe
Starting program: /usr/bin/mono /my/path/lib/banshee/banshee.exe
Reading symbols from shared object read from target memory...done.

this is not allowed. You must explicitly end the data stream to the

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1208133936 (LWP 24942)]
0x0032d4c3 in ?? ()

Then the backtrace :

(gdb) bt

#1  0x00000000 in ?? ()
(gdb) p mono_print_method_from_ip 0x0032d4c3
A syntax error in expression, near `0x0032d4c3'.
(gdb) p mono_print_method_from_ip (0x0032d4c3)
IP 0x32d4c3 at offset 0x53 of method DBus.Bus:GetBus (DBus.Bus/BusType) 
(0x32d470 0x32d518)[domain 0x21f00 - banshee.exe]
$1 = void
(gdb)

So....I guess the seg fault has something to do with DBus, or bus error 
of some sorts.

As far as I can see I have all the correct packages.

dbus-devel-0.61-3.fc5.1
dbus-x11-0.61-3.fc5.1
dbus-0.61-3.fc5.1
dbus-python-0.61-3.fc5.1
dbus-debuginfo-0.61-3.fc5.1
dbus-sharp-0.61-3.fc5.1
dbus-qt-0.61-4.fc5
dbus-glib-0.61-3.fc5.1
dbus-qt-devel-0.61-4.fc5

Does this shed any light on the issue.....because I'm still in the dark !!

cheers
Neil
