           Summary: hanging dialogs in KDE
           Product: kde
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: sf_knue at web.de


Version:            (using KDE 4.2.3)
OS:                Linux
Installed from:    Gentoo Packages

Sometimes the dialogs in KDE hang. Here is one I can currently reproduce:
1. fire up kwrite
2. write something
3. close
-> The application hangs for a couple of seconds till the dialog shows up.

Have a look at my strace output from:
strace kwrite 2> kwrite_log

The hanging starts exactly at:
gettimeofday({1243469810, 680552}, NULL) = 0
poll([{fd=8, events=POLLIN}], 1, 25000) = 1 ([{fd=8, revents=POLLIN}])
read(8, "l\2\1\1\v\0\0\0\1\0\0\0=\0\0\0\6\1s\0\6\0\0\0:1.895\0\0\5"..., 2048) =
262
read(8, 0x6d4c10, 2048)

in line 1844 of the file.

Sometimes I get in dialogs of applications an empty dialog box with no text nor
buttons (have a look at the screenshot). It takes a couple of seconds till the
text shows up. I belief this is the same bug. Unfortunately this one is hard to
reproduce so I don't have an strace output.
