Could you look into the above glib error too? I sent a mail about 
that earlier.


        Hi,
I'm sorry, but no. I told you, also earlier, that the bug is not in 
Evolution, it's in WebKit. Get a backtrace [1] from it and you'll see 
it yourself. There is nothing Evolution can do with it, except stop 
using WebKit, which won't happen.

[1]   $ gdb evolution --ex r --ex "b g_logv" --ex c --ex bt --ex c
    which runs evolution, then let it finish its initial duties, find
    a way to reproduce the critical warning, then press Ctrl+C once in
    the terminal, which will set the breakpoint, then reproduce
    the warning and if it'll be the first hit, then the shown backtrace
    will provide info from where the warning comes. Feel free to repeat
    the pair of commands "c" followed by "bt" to get more backtraces.
    Quit gdb with a "q" command. As I said in the previous thread,
    it's better to know, than to guess.


After struggling with building webkit with debug sysmbols I managed to
get at backtrace from gdb using the gdb command above, I hope
you can make something out of it.
