i have gtk-engines-qt-0.6-r2 and work perfectly. used it with firefox 1.0.7 with no troubles. upgrading to firefox 1.5 i have: lots and lots of: (Gecko:2428): Gdk-CRITICAL **: gdk_pixbuf_get_from_drawable: assertion `gdk_window_is_viewable (src)' failed (Gecko:2428): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_n_channels: assertion `pixbuf != NULL' failed (Gecko:2428): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_bits_per_sample: assertion `pixbuf != NULL' failed (Gecko:2428): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_width: assertion `pixbuf != NULL' failed (Gecko:2428): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_height: assertion `pixbuf != NULL' failed (Gecko:2428): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_rowstride: assertion `pixbuf != NULL' failed (Gecko:2428): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed some gui part are not perfect. firefox seems to runs slow. changing the gtk2 theme to another fixes all.
seems same problem with thunderbird, mozilla, nvu...whole mozilla things ...
mozilla-firefox-1.5.0.4 and gtk-engines-qt-0.6-r2 From this forum post: http://forums.gentoo.org/viewtopic-t-468565.html Every five minutes or so, Firefox "hiccups" (freezes), and the tab you're looking at goes blank. This generally lasts about 2-30 seconds, with FF using 80-90% CPU all the while. Then all goes back to normal - with the exception of the page you were looking at being scrolled back up to the top. This is often accompanied by a memory leak of around 50mb in the X process, and occasionally (this has happened to me a couple of times in the last 2 days) it crashes out of control - the first time this happened X was eating around 1.5Gb of memory. If you reset X with Ctrl-Alt-Backspace the memory is freed. Apparently the problem can be solved by unmerging gtk-engines-qt.
unmerging not needed...just don't use that theme, but a normal gtk2 one. however something's broken. where...i don't know. all mozilla derived apps have same problem, but i have slightly different problems with other apps too (just 1-2-3 warnings, instead of mozilla flood)
I added a new gtk-engines-qt cvs snapshot, hopefully it can help you.
