Status changed to 'Confirmed' because the bug affects multiple users.

This broke for me too, on the last update of Kubuntu.

I built from source, and it was still broken.

Got a backtrace:

Program received signal SIGSEGV, Segmentation fault.
QBasicAtomicInt::ref (this=0x0) at /usr/include/qt4/QtCore/qatomic_x86_64.h:121

Don't understand the why yet, but modifying line 22 from plugin.cpp from

const QString Plugin::S_TOKEN_SEPARATOR = TokenHelpDialog::S_TOKEN_SEPARATOR;

to

const QString TokenHelpDialog::S_TOKEN_SEPARATOR = ";;";

allows KRename to be built, and run successfully.

I don't know C++ well enough to understand why. But it fixed it for me.

To build your own, download the source:
http://sourceforge.net/projects/krename/files/KDE4%20krename-stable/4.0.7/krename-4.0.7.tar.bz2/download

extract, then execute (inside the folder):

cmake
make
sudo make install
