seems the crash happens during malloc of 16K bytes. Probably due to a memory corruption. Hard to say how that happened. Can you reproduce it?
I have a bridge set up on my wired network connection. I can reproduce the crash every time by opening up the network settings, going into the bridge settings, opening up the settings for a bridge connection, and then cancelling out of all the windows without changing anything. If I run nm-connection-editor using Valgrind I get some memory errors when opening the bridge settings: ==25349== Invalid read of size 4 ==25349== at 0x772C535: g_array_unref (in /usr/lib64/libglib-2.0.so.0.5000.2) ==25349== by 0x135BE9: ???

*** Bug 1418101 has been marked as a duplicate of this bug. ***
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
