Description Alec Moskvin 2009-04-25 06:34:29 UTC 
Version:            (using KDE 4.2.2)
Compiler:          gcc (Gentoo 4.3.3-r2 p1.1, pie-10.1.5) 4.3.3 
OS:                Linux
Installed from:    Gentoo Packages

How to Reproduce:
1. Open a terminal and run:
 $ mkfifo mypipe
2. Open dolphin or konqueror to the direcory where you made the pipe.
3. Try to right click mypipe and select "Properties"

Result:
The application freezes as it waits for the pipe to release data.

If there actually is something writing into the pipe, dolphin reads and subsequently destroys the data.

Expected Behaviour:
Pipes are not regular files and should not be treated as such.

confirmed in trunk too.
Comment 2 Dario Andres 2009-05-24 21:06:29 UTC 
http://reviewboard.kde.org/r/723/ should fix this

SVN commit 979879 by darioandres:

Add KFleItem::isRegularFile() to check for regular files (!chr/blk/dir/fifo/link/sock)

Do not fetch the metadata information on non-regular files as this will likely 
block the application when reading them.
