I have a weird and puzzling problem with thunderbird on my main computer, running Fedora 26 (waiting for resolution before updating). If I so much as touch an attachment to a received email, the machine freezes. That is, the kernel refuses to start any more new processes, however, it continues to run the existing ones. I can switch to a different Xfce4 workspace, or simply move the mouse to activate a window that overlaps the thunderbird window. However, the thunderbird window is dead and won't refresh itself. Only a reboot fixes it. Today I received an email with an OO spreadsheet attached. I was able to click to save it successfully, but then the machine was frozen. My numerous gkrellm graphs continued to blink, but in another terminal I could not even ls, or cd to another directory, and typing reboot had no effect. I was able to kill the X server with CTL-BS and achieve a black screen with a jumbled mess of systemd gook. On a different console (ALT-F2) I got a login prompt, then a passwd prompt, but that's as far as login got. I had to resort to the ultimate weapon: SysReq + REISUB, of which only the first three, REI, were sufficient, so sending the SIGKILL signal to all processes unstuck the machine. This problem affects ONLY my main machine; with all the others in the house, thunderbird handles attachments perfectly. FWIW, mutt handles the attachment without complaint. This problem has persisted over many kernel updates; it may have been present even in Fedora 25. I strongly suspect I have some odd plugin or addon on this machine only. But before I start a massive witchhunt, I want to ask the experts here: Has anyone experienced a similar breakdown? -- David A. De Graaf DATIX, Inc.
