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 Andrew Mike 2020-01-10 18:48:07 UTC
Description of problem: While freerdp, running in GNOME 3, is connected to a Windows VM in windowed graphical mode, it crashes on keyboard input after switching workspaces.

Version-Release number of selected component (if applicable):
2.0.0-1.rc4.el7

How reproducible: Sporadically (see notes).

Steps to Reproduce:
1. Start freerdp by connecting to a Windows VM.
2. Switch to another workspace in gnome without the freerdp window on it.
3. Switch back to the workspace by pressing the Ctrl+Alt+arrow keys.
4. Press the Enter key.

Actual results: X crashes with an application core.

Expected results: freerdp, GNOME, and Xorg continue to function.

Additional info:
- Attempts to reproduce this while the freerdp was connected to a physical Windows 10 machine were unsuccessful.
- Switching workspaces with the mouse does not reproduce the issue.
- This happens whether GNOME is in Classic Mode or not.
- Efforts to reproduce this with KDE failed.
- This is reproducible while freerdp is connected to either Windows 10 or Windows 7 VMs.

I am not able to reproduce it on my RHEL 7.7 when connecting to Windows Server 2016 VM.

The attached coredumps seem to be both for ibus-daemon and it looks like Bug 1350291, which was probably fixed by https://src.fedoraproject.org/rpms/ibus/blob/d4486513e9315268e0d957c77d5d14d7eb83e0fe/f/ibus-1385349-segv-bus-proxy.patch in Fedora. But this is probably just consequence of the session crash. Can you please reupload the data for xorg?

Does it help if you downgrade to freerdp-1.0.2-15.el7, or when this started happening?

This is maybe related to https://bugzilla.redhat.com/show_bug.cgi?id=1659113.

Managed to produce an xorg coredump using freerdp-2.0.0-1.rc4, attached. I wasn't able to get a VM set up with the downgraded freerdp; I'll see if I can get to that next week. Apologies for the delay.

Comment 6 Ondrej Holy 2020-02-05 10:00:50 UTC
Thanks for the coredump. It looks like to me as a duplicate of Bug 1659113 given the backtrace. It is most probably the same as Bug 1677719 and Bug 1671183. Apparently also tigervnc and x2go have the same issue.
