           Product: konsole
           Version: 3.90.900
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR

build error log

*Environment:
 - Gentoo kernel 3.17.8-gentoo-r1
 - Clang 3.5.0-r100
 - Qt5 dev branch from git source (not portage tree)

*How to reproduce:
 - Build konsole with qt5 dev branch ( with ./kdesrc-build --refresh-build
konsole)

*Behavior to expected:
 - Build succeeded

*Behavior in fact:
 - Build failed with error " ProcessInfo.cpp:448:37: error: call to member
function 'readLine' is ambiguous "

*Route cause:
 - As QtTextStream::readLine() has been overloaded in Qt5 dev branch[1]
readLine(0) is detected as ambiguous.

*Suggestion to fix:
 - call readLine() without no arg to be set maxlen=0 as default. (see attached
file)
