Wireshark · Wireshark-bugs: [Wireshark-bugs] [Bug 11400] Cannot launch GTK+ version of wireshark as a normal user

[bugzilla-daemon@xxxxxxxxxxxxx]

Comment # 4 on bug 11400 from jean-christophe manciot

Yes, the behavior is a little different in both situations:
- the crash happens right away when dumpcap owner & group are NOT modified
(root:root)
- the Glib & GTK critical messages disappear when dumpcap owner & group ARE
modified (username:wireshark) and wireshark is launched with
"LIBOVERLAY_SCROLLBAR=0 wireshark". The crash happens when trying to start a
capture on an interface that is not denied to the user.
