The GtkLauncher crashes when clicking on any row in the inbox view of Google Mail/Gmail. So does Epiphany built upon the same Webkit trunk (35231). Clicking on the row also does not mark the mail as read. As a sidenote: Google Reader works just fine when doing a similar operation (i.e. opening an item for viewing) Revision 35321 Debian Lenny/testing
works perfect now. Seems already fixed.
This bug is based on a really old WebKit revision and AFAIK works as it should in the recent WebKitGtk releases (and with ToT).
