Re: [Evolution] assertion 'flags & FLAG_INITIALIZED' failed

Hi,

I replaced the WebKitWebProcess, and i obtain this :

[pascal@PC-INFO-LINUX001 lib]$ evolution

And Evolution stop working.

When i shearch in /var/log any log of the crash, i don't find anything.
But I don't know what i must search.

Thanks

ah, good to know it's not a new thing. (The 2.26.x has plenty of
regressions/changes, which break some applications.)

That can be something either in your ~/.config/gtk-3.0/gtk.css or in
your desktop theme. You are right, it's unrelated.

Right, it's not an easy thing and things can break easily. If you'd
like to give it a try with below steps, then you can, but if unsure,
then rather do not do it.

I've been thinking of doing this as root, supposing the WebKitWebProces
is stored in /usr/libexec/webkit2gtk-4.0/:
a) go to the directory with the file:
   # cd /usr/libexec/webkit2gtk-4.0/
b) rename original file:
   # mv WebKitWebProcess WebKitWebProcess.orig
c) create a file WebKitWebProcess at the same directory with this
content:

   #!/bin/bash

   G_DEBUG=fatal-warnings /usr/libexec/webkit2gtk-
4.0/WebKitWebProcess.orig "$@"

d) set executable attributes to the new script:
   # chmod a+x WebKitWebProcess

And now, when you run Evolution, it should execute the script and
eventually crash the WebKitWebProcess.orig when the warning will be
shown. The interesting part is the backtrace of the crash. Where it is
stored in your distribution I do not know.

To revert the changes simply do this as root:
e) go to the directory with the file:
   # cd /usr/libexec/webkit2gtk-4.0/
f) rename the original file back:
   # mv WebKitWebProcess.orig WebKitWebProcess

Or you can reinstall/update webkit2gtk3 package, which will overwrite
the WebKitWebProcess script.

        Bye,
        Milan
