Do you see any error messages if you run icedove from an X terminal? You should also check ~/.xsession-errors.
Nothing in the terminal or in the .xsession-errors Did you really complete the upgrade or did apt list some packages as
"kept back"? If you have aptitude installed you can use aptitude search '~U' | wc -l
No packet kept back Also tell us which version of icedove you are currently using.
(Run "apt-cache policy icedove" to find out.)
n75:/home/fabrice# apt-cache policy icedove icedove: Installed: 2.0.0.4.dfsg1-1 Candidate: 2.0.0.4.dfsg1-1 Version table: *** 2.0.0.4.dfsg1-1 0 500 http://ftp.fi.debian.org unstable/main Packages 100 /var/lib/dpkg/status I tried to display the window on another computer (with DISPLAY=other:0.0icedove) and everything works correctly. Can it be something with the configuration of xorg?
