** Tags added: i386 ** Description changed:
Filezilla and Agender are unrelated desktop applications, except that they both use wxWidgets. Filezilla is an ftp/sftp client, and Agender is a planner/scheduler. On a Lubuntu Desktop session (that is, with LXDE as the desktop environment), I minimized Filezilla to its notification area icon (so that icon was its only accessible interface element). Then I killed lxpanel with SIGTERM (to simulate a crash), and restarted it by running the command "lxpanel --profile Lubuntu" in an LXTerminal window. Filezilla's notification area icon was gone, but running "pidof filezilla" revealed that Filezilla was still running (now inaccessibly) in the background. I then terminated Filezilla with SIGTERM, logged out and back in, and repeated this test with Agender instead of Filezilla. Agender's notification area icon was also missing, and Agender was also still (now inaccessibly) running. - I then killed Agender, logged out and back in, and repeated test with - Pidgin. Pidgin uses GTK+ directly; it does not use wxWidgets at all. - Pidgin's notification area icon was present in the newly restarted - lxpanel (which is the expected/desirable behavior). + I then killed Agender with SIGTERM, logged out and back in, and repeated + test with Pidgin.

The above tests were conducted on a Maverick i386 system with the following possibly relevant packages/versions: lubuntu-desktop 0.18.1 lxpanel 0.5.6-0ubuntu2 filezilla 3.3.3-1ubuntu1 libwxgtk2.8-0 2.8.11.0-0ubuntu4 libwxbase2.8-0 2.8.11.0-0ubuntu4 libglib2.0-0 2.26.1-0ubuntu1 pidgin 1:2.7.3-1ubuntu3.2 Since Agender is not provided by any Ubuntu package, I built and installed it from source, using the default configuration. I used version 1.1.9. I conducted this test after having filed this bug report against the filezilla package, and being advised by Adrien Cunin that I should test another wxWidgets application with a notification area icon. The original version of this bug report was from a different system, running Maverick amd64. It indicated version 1.207 of lubuntu-desktop, which seems to be in error, since the current version is much lower. It indicated the same versions of the filezilla and lxpanel packages as on the Maverick i386 system described above (and did not give information about versions of any other packages). Therefore, this bug is not limited to i386. Furthermore, it is also not limited to artificially induced lxpanel termination--while the original bug report did not mention this, I initially found this problem when lxpanel crashed (with SIGSEGV, from bug 690932). On that system, I had observed that the notification area icons of other non-wxWidgets-using applications (besides Pidgin) to survive lxpanel restart. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/691905 Title: notification area icons do not survive lxpanel restart -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
