Bug#1025332: Subtle build failure

[Gunnar Hjalmarsson <gunnarhj@debian.org>]

package: src:ibus-cangjie
version: 2.4-6
severity: serious
tags: ftbfs

The buildlog in unstable (on all) states:

make[1]: *** [debian/rules:23: override_dh_auto_test] Error 1

Tail log to give context:

# SKIP:  0
# XFAIL: 0
# FAIL:  0
# XPASS: 0
# ERROR: 0
=====================================================================

make[4]: Leaving directory '/<<PKGBUILDDIR>>'
make[3]: Leaving directory '/<<PKGBUILDDIR>>'
make[2]: Leaving directory '/<<PKGBUILDDIR>>'

make[1]: *** [debian/rules:23: override_dh_auto_test] Error 1
make[1]: Leaving directory '/<<PKGBUILDDIR>>'
make: *** [debian/rules:17: build-indep] Error 2

ibus-cangjie 2.4-5 built successfully in September, and the only
package file which has changed since then is debian/watch.

I can't reproduce the build failure locally in Debian testing or
Ubuntu development environments.
