When 
KDE_FORK_SLAVES=1
is set, kmail freezes when clicking on (external) links.
Comment 1 Michael Nottebrock 2004-09-01 06:07:21 UTC 
Confirmed on FreeBSD.
Comment 2 Hans Oischinger 2004-09-05 20:45:00 UTC 
This also happens when clicking on links in kopete and basket
Comment 3 Rex Dieter 2004-09-05 20:57:15 UTC 
Updating summary/product as it seems KDE_FORK_SLAVES is inherently broken (at least in kde 3.3.0).

I can confirm this bug under KDE3.3

This bug is still present in kmail 1.9.7 / KDE 3.5.8 (tested on Debian unstable).

It seems to block on a socket read:
strace:
10261 read(3, "\1\0\0\0", 4)            = 4
10261 read(3, "\0\0\0\vDCOPServer\0\0\0\0\1\0\0\0\0\1\0\0\0\0\35app"..., 83) = 83
10261 read(3,

For giggles, tried to reproduce on kde.4.3.0.

kmail/kontact does still block on opening http links, but only a short time, 10-20 seconds (or so), then konq pops open and things return to normal.

All other uses *seem* to be ok so far.

Can this ticket get closed then since you stated that it worked okay when tested in KDE 4.3.0 ? It should work even better in KDE 4.5.0 since the new scheduler was merged in that release.
Comment 8 Rex Dieter 2011-11-04 12:20:36 UTC 
OK, stick a fork in it.
