it works fine with qemu 0.15.1, even when built with the same versions of 
glib2.0 as as qemu 1.x branches. so that would seem a bit odd... unless qemu 
1.x is using more of glib2.0 than qemu 0.15.

would that then essentially come down to tracking down all of glib2.0's build 
dependencies and installing those as well?

hrm. would like to see it working again, though it's a bit over my head.

Title:
  qemu-user -static variants require shared libraries

Status in QEMU:
  New
Status in “qemu” package in Debian:
  New

Bug description:
  somehwere in the qemu 1.0 series, the qemu-user static  variants
  started issuing build warnings like so:

    
/usr/lib/gcc/i486-linux-gnu/4.6/../../../i386-linux-gnu/libglib-2.0.a(gutils.o):
 In function `g_get_any_init_do':

  for a full log, see:

  
https://buildd.debian.org/status/fetch.php?pkg=qemu&arch=amd64&ver=1.0~rc4%2Bdfsg-1&stamp=1322591568

  i've also tested with qemu/master from today (commit
  217bfb445b54db618a30f3a39170bebd9fd9dbf2), and it has the same issue.

  This seems to cause adduser, addgroup, etc. to fail in cross-
  architecture chroots that use statically built qemu-user binaries to
  emulate the foreign architecture.

  Older versions (0.12-0.15, at least) didn't seem to have this issue.
