[Bug 1803808] Re: wireshark crashed with SIGSEGV in QIcon::~QIcon() under Unity

[Stdedos]

According to the reproduction:
https://bugs.launchpad.net/ubuntu/+source/wireshark/+bug/1803808/comments/3

> 1. Start the Qt GUI
> 2. Close the application using the window's close icon on the title bar (x).

I don't see the issue replicated.


Unfortunately, I forgot to close the "official" wireshark by pressing (x); I 
used Ctrl+Q.
Hence, I am 98% sure that the issue was fixed (and not 99%). Basic/Normal 
functionality of opening and browsing pcap files seems unaffected.

I'll try to remember to re-test again when I ppa-purge (when the package
starts actually moving towards -security); I am keeping it for now

@lekensteyn Thanks! As a side note upgrade to 3.0 is not an option for many 
users yet since 3.0 is waiting for approval in Debian's NEW queue.
I'll be happy to include the fix in Wireshark's next security update though, 
thus users get this fixed automatically.

I was not able to reproduce this issue with a Wireshark build from git
using `cmake -GNinja -DCMAKE_BUILD_TYPE=Debug -DENABLE_ASAN=1
~/wireshark && ninja wireshark`:

* master v3.1.0rc0-1166-g1e7f85e02f66
* master-3.0 v3.0.3rc0-46-gd094b56a9b4e

I can reproduce the crash with the same build settings and:

* master-2.6 v3.1.0rc0-1168-gc0822c187b

No idea what has changed since 3.0, but I guess you can safely upgrade
to Wireshark 3.0 now to fix this issue.

[Bug 1803808] Re: wireshark crashed with SIGSEGV in QIcon::~QIcon() under Unity

[Mikael Kanstrup]

Hi,

I was trying to find a cause for this crash before finding this bug item
reported here. After reading the comments I wanted to give some info on
what I've found.

I'm running Ubuntu 16.04 and experience the problem with latest
Wireshark on master branch. I noticed it a few weeks back but didn't
find time to investigate it until now. Bisecting the problem I found
that the crash was introduced with the following change in Wireshark:

2cfa301 Qt: Create the main display filter combo sooner.

This change is also present on 2.6 from 2.6.3 and on cherry-picked as:

3a0da5f Qt: Create the main display filter combo sooner.


Removing appmenu-qt5 package didn't help for me. Neither did installing 
gtk2-engines-oxygen package.

A possible other workaround that works on Xenial, too, is removing the
appmenu-qt5 package until appmenu-qt5 is fixed.
