RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Vladimir Benes 2016-04-28 12:52:37 UTC 
This bug has been created based on an anonymous crash report requested by the package maintainer.

Report URL: http://faf.lab.eng.brq.redhat.com/faf/reports/bthash/b2d302feb13eb7fd27ffebb0313c2b0f3b304f53/

reproducer: 
call('yum -y install usb_modeswitch ModemManager', shell=True)
call('systemctl restart ModemManager.service', shell=True)
call('for i in $(ls /sys/bus/usb/devices/usb*/authorized); do echo 0 > $i; done', shell=True)
call('for i in $(ls /sys/bus/usb/devices/usb*/authorized); do echo 1 > $i; done', shell=True)
sleep(15)
^^ this is very important changing to 20 and everything behave OK.

then test adds new novice mode connection for gsm device
    * Open wizard for adding new connection
    * Expect "Connection type"
    * Submit "gsm" in editor
    * Expect "Interface name"
    * Enter in editor (this means no device specified)
    * Expect "APN"
    * Submit "internet" in editor
    * Expect "Do you want to provide them\? \(yes\/no\) \[yes\]"
    * Submit "no" in editor
    * Expect "Do you want to add IP addresses\? \(yes\/no\) \[yes\]"
    * Submit "no" in editor
## crash is here when NM autoconnects created connection 
    * Bring "up" connection "gsm"
    Then "gsm" is visible with command "nmcli con show -a" in "10" seconds
     And Ping "redhat.com"

FAF was misconfigured so it did not accept adding URLs to the report. This was fixed and deferred attachments were added to the reports so they're complete now.

I think the finish functions should always be called.

like:

if (!mm_sim_send_pin_finish (sim, result, &error)) {
    if (g_error_matches (error, G_IO_ERROR, G_IO_ERROR_CANCELLED)) {
        return;
    g_return_if_fail (self->priv->ctx && self->priv->ctx->step == 
                      CONNECT_STEP_UNLOCK);
    /* process failure... */
    return;
}
g_return_if_fail (self->priv->ctx && self->priv->ctx->step == 
                  CONNECT_STEP_UNLOCK);
/* process success... */

typo: "suririse"


otherwise, lgtm.


(I would use NM_IN_SET(new_state, NM_DEVICE_STATE_FAILED, NM_DEVICE_STATE_DISCONNECTED), but as you prefer).
