Hi. I'm trying to connect to internet using my E3276 4G modem. But I cannot
'cause of strange error -- 'ip-config-unavailable'. Modem works well under
Windows, when using official "connect manager" software. Here's output of
'NetworkManager --no-daemon' command. Output is generated with last,
downloaded from git repo and compiled from sources (last commit is
47d8db5) version of NM. I've also tested with 0.9.8.0 and 0.9.6.4 versions,
but result is the same.

N.B. I've done some hacking and re-compiling on 0.9.8.0 version and figured
out, that function, that actually outputs the error is
'nm_device_activate_ip4_config_timeout' in 'nm-device.c' file, and one of
it's lines is notably different in very last (commit 47d8db5) and 0.9.8.0
versions:
comm. 47d8db5:
if ((priv->ip4_state == IP_DONE) && (priv->ip4_config == NULL)) {
ver. 0.9.8.0
if ((priv->ip6_state == IP_DONE) && (priv->ip6_config == NULL)) {
Hope this will help. Thanks in advance!
