[Bug 909179] [NEW] [Precise] Ubiquity uses up all memory and hangs during installation

[Geir Ove Myhr]

Public bug reported:

During installation, after entering the user information, the installer
slows down to a crawl and the status bar (which says "Copying files")
stops. Upon switching VT to 2 and back to 7, the window contents is not
updated. Checking with top, the ubiquity process uses 70-95% CPU and
after a while 750 M (of 1 G) of real memory and 3.5 G (of 4.0 G) of
virtual memory.

The information uploaded with apport-collect is from the same LiveUSB
session after I killed the ubiquity process an hour or two after it
first hung. Apport wanted to submit a bug report automatically when the
unity session started, but that bug report was wrongly judged to be a
duplicate of bug 652916.
