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.

Hello, thank you for the report. I have submitted a patch for review:
https://github.com/abrt/libreport/pull/269

and prepared the following scratch build with the patch already applied:
http://koji.fedoraproject.org/koji/taskinfo?taskID=7190504

Could you please install the packages, retest and report the results here:

$ cd /var/tmp/abrt/ccpp-2014-07-23-12:42:37-4199
$ reporter-ureport

--- Additional comment from František Dvořák on 2014-08-17 11:07:46 CEST ---

I can confim the crash in 2.2.3-1.fc20. The koji build results are inaccessible.

Thanks, I can confirm the patch fixes the crash.

--- Additional comment from David Juran on 2014-08-22 14:22:31 CEST ---

With my reproducer, libreport no longer crashes but it doesn't complete either. Running reporter-ureport -vvvv from the command line runs for a few minutes and then exits with status 1. From within abrt, I get
 --- Running report_uReport ---
 Server responded with an error: 
'uReport may only be 4194304 bytes long' reporter-ureport failed with exit code 1 ('report_uReport' exited with 1)

David, thank you for the analysis, you hit another bug in satyr. Could you please open a new bug against satyr for the new issue? And please remove the negative karma [1] from the update, it blocks the GUI enhancements.
