What am I doing wrong? KCrash: crashing... crashRecursionCounter = 2

plaws@toto:plaws $ /usr/bin/lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 11.04 Release: 11.04 Codename: natty kdesktop-trinity 4:3.5.13-1ubuntu0+ax3~natty Just updated FF and TBird to 16.0.1 out of the repos. Can't launch either from their icons. When I try either from the command line, I get: plaws@toto:plaws $ firefox KCrash: crashing... crashRecursionCounter = 2 KCrash: Application Name = gtk-qt-application path = <unknown> pid = 47697 Memory fault laws@toto:plaws $ thunderbird KCrash: crashing... crashRecursionCounter = 2 KCrash: Application Name = gtk-qt-application path = <unknown> pid = 47862 Memory fault To run them, I used: LD_PRELOAD=/opt/trinity/lib/kgtk/libkgtk2.so Clearly, I have something mis-configured, but what? Where should I look first? -- Peter Laws / N5UWY National Weather Center / Network Operations Center University of Oklahoma Information Technology plaws(a)ou.edu College of Architecture, Regional and City Planning, MRCP '16 -------------------------------------------------------------------------- Feedback?
