[Pkg-bazaar-maint] Bug#438745: bzr-gtk: "Log" action takes forever in olive-gtk

[Roland Mas]

Package: bzr-gtk
Version: 0.18.0-1
Severity: normal

Running olive-gtk in a freshly checked-out branch of bzr.dev and
clicking on the "Log" button takes ages before displaying anything.
The process has used more than 45 minutes of CPU time (not wallclock
time) so far on this Athlon XP @1.8 GHz, and I still haven't seen the
first line of log.  iostat(1) tells me the system is not swapping,
there's no data being read from the disk, the LEDs on the switch tell
me there's no network activity...  Yet olive-gtk still happily keeps
eating my CPU time and showing nothing.  I eventually interrupted it,
so I can't tell exactly how long it takes before the log appears, but
it's not something I would call fast enough (as in "fast enough for
most projects").

(What makes this bug even more frustrating is that in the meantime, I
found out about "bzr viz", which starts showing the log after about 30
seconds of CPU time.)

If that helps, the backtrace I got when I interrupted the process was:
