Hmmm, it seems that this bug exists *only* in Ubuntu and not in Debian.
Ubuntu source package contains a patch that rewrites the
usb_modeswitch_dispatcher program from Tcl to C. While there must have
been good reasons to do this, there is at least one more bug in the
rewritten version.
On line 422 in file usb_modeswitch_dispatcher.c there is an assignment
of NULL to a char pointer. This pointer is later passed to printf when
forming the usb_modeswitch command. Therefore there should be strdup("")
instead of null pointer, as now usb_modeswitch is launched literally
with "(null)" argument produced by printf.
Would it be possible to remove the rewrite and switch back to Tcl (at
least for new releases of Ubuntu)? It seems that the upstream package
has switched to some lightweight Tcl interpreter (Jim). This could
remove some of the reasons why it had to be rewritten (extra
dependencies, boot time?).
