Hi, I have the same problem in debian testing with QT 5.4 and also with the new qt5.5.1 which I got as a normal update today. Here is the issue: https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=11643 Here someone else reported the same problem some time ago: https://www.wireshark.org/lists/wireshark-bugs/201505/msg00563.html Hauke ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev@wireshark.org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-requ...@wireshark.org?subject=unsubscribe
