I have the same error: I downloaded the opera browser to test (I rather prefer an open source browser) from the opera-website in Firefox.
I chose "open with GDebi Package installer" for the opera_10.10.4742.gcc4.qt3_i386.deb file, and not "save file.." after a while, the package installer said, "file not found anymore" or something like that After that I got the nautilus problems. First I got the (nautilus:2632): Eel-CRITICAL **: eel_preferences_get_boolean: assertion `preferences_is_initialized ()' failed error After the Erez Volk's PPA (didn't work for me): b...@pcthuis:~/Bureaublad$ nautilus Initializing nautilus-gdu extension ** (nautilus:2393): WARNING **: No marshaller for signature of signal 'UploadFinished' ** (nautilus:2393): WARNING **: No marshaller for signature of signal 'DownloadFinished' ** (nautilus:2393): WARNING **: No marshaller for signature of signal 'ShareCreateError' Segmentation fault Maybe it's the curse that rest on proprietary software? :-) -- eel_preferences_get_boolean: assertion `preferences_is_initialized ()' failed https://bugs.launchpad.net/bugs/454234 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
