creator hangs when clicking a certain build issue

i compiled something, got the following errors:

.obj/debug-shared/tst_qprocess.o: In function `tst_QProcess::execute()':
/depot/obuddenh/qt-4.7/tests/auto/qprocess/tst_qprocess.cpp:296: undefined reference to `bool QTest::qCompare<int, bool>(int const&, bool const&, char const*, char const*, char const*, int)'
collect2: ld returned 1 exit status

this yields three items in the issues list:

• the .o file without line number
• the .cpp file with line number
• the "collect2" error

clicking the second item works. clicking the first item results in creator hanging with the following backtrace:

the actual hang is in the text editor, but the root cause seems to be that it tries to open the binary file as a text file in the first place.
