Hi

On loading Quanta up I'm finding that CPU usage is jumping to 99.9%. An
strace on the Quanta pid is giving information about "gettimeofday"
I know it's happening when my CPU fan starts running hard... :) The high CPU
usage lasts for about 30-60 seconds then drops to normal.

strace ->

gettimeofday({1178276607, 657470}, NULL) = 0
ioctl(5, FIONREAD, [0])                 = 0
write(6, "\0", 1)                       = 1
gettimeofday({1178276607, 657596}, NULL) = 0
write(3, ";\3\5\0+\4`\2\0\0\0\0\0\0\0\0f\0\17\0\235\6\5\0O\t`\2\0"..., 1572)
= 1572
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1178276607, 657942}, NULL) = 0
select(18, [3 4 5

etc etc

Any ideas what could be causing this. It's only started to happen in the
last week or so and Quanta hasn't been updated in a while.
I searched on bugs.kde and nothing much came up Quanta related.

Specs:

Kubuntu 7.04
KDE 3.5.6-0ubuntu20 (kubuntu packages)
Quanta/kdewebdev 3.5.6-0ubuntu1 (kubuntu packages)


Cheers
James
