Hi
Thanks for the answer. If this issue is fixed on more recent versions
that's fine, I'm planning anyway to upgrade my debian in a few weeks.
Just in case someone wants to investigate more, here's the asked backtrace
(after installing package libglib2.0-0-dbg :-)

(gdb) bt
#0  0x00007fda7bf96870 in read () from /lib/libc.so.6
#1  0x00007fda7c4b9ca2 in g_io_unix_read (channel=0x26ca910, buf=0x27f4340 "", count=1024, bytes_read=0x7fff1f1ad308, err=0x7fff1f1ad390)

#7  0x00007fda7ed72a60 in ?? ()
#8  0x0000000000000000 in ?? ()

So it seems indeed that the program is stuck in a blocking read, for whatever reason...
Well, let's say for now that Glib.Io.read is the winner ;-)
