By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description Julius Schwartzenberg 2013-07-11 13:19:12 CDT 
With the current nightlies on Ubuntu Quantal, when loading the new package and status information, adept uses a lot of CPU (~100%) and it takes very very long compared to the current release. Once adept is passed this phase and while downloading and installing updates, everything is normal.

When I look at the process with strace, I get a lot of this:
recvfrom(3, 0xd8e3c4, 4096, 0, 0, 0)    = -1 EAGAIN (Resource temporarily unavailable)
recvfrom(3, 0xd8e3c4, 4096, 0, 0, 0)    = -1 EAGAIN (Resource temporarily unavailable)
recvfrom(3, 0xd8e3c4, 4096, 0, 0, 0)    = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=8, events=POLLIN}, {fd=3, events=POLLIN}, {fd=6, events=POLLIN}, {fd=4, events=POLLIN}, {fd=10, events=POLLIN}, {fd=78, events=POLLIN}, {fd=80, events=POLLIN}], 7, 0) = 0 (Timeout)
recvfrom(3, 0xd8e3c4, 4096, 0, 0, 0)    = -1 EAGAIN (Resource temporarily unavailable)

Adept will be dropped from R14.1. Closing as wontfix.
