Not sure if there is another way of reporting issues in ArchLinux; did
you try to report the issue to them directly?

Some rough steps to follow:
 * Compile MM with debug symbols; I guess in ArchLinux you can take the
following file:

https://projects.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/modemmanager
and then add "CFLAGS=-ggdb -O0" (including quotes) after the
--disable-static option passed to configure.

 * Once compiled and installed, run it under gdb:
   $> sudo gdb --args /usr/sbin/modem-manager --debug

 * Reproduce your problem and wait for gdb to tell you about the
segfault. Once you have that, just run "bt" (inside gdb).

Then include in your email the output of the gdb command as well as the
ModemManager debug logs.

Cheers!
