[kde-freebsd] process stuck in "umtxn"

[Mikhail T.]

Hello!

I noticed, that my build of KDE4 ports got suspiciously quiet...
Pressing Ctrl-T shows:

    load: 0.01  cmd: automoc4 78507 [umtxn] 0.00u 0.00s 0% 3552k

According to gdb, the process' stack is:

    #0  0x0000000800d9620a in __error () from /lib/libthr.so.3
    #1  0x0000000800d95f0c in __error () from /lib/libthr.so.3
    #2  0x0000000800d911eb in pthread_mutex_getyieldloops_np () from
    /lib/libthr.so.3

    #6  0x000000080073f2c6 in QProcess::start () from
    /opt/lib/qt4/libQtCore.so.4
    ....

My system is 7.2-PRERELEASE/amd64 from April 9th. Please, advise.
Thanks! Yours,
