While Konsole indeed works now, the kpty tests are still failing:

Config: Using QtTest library 5.7.1, Qt 5.7.1 (x86_64-little_endian-lp64 shared
(dynamic) debug build; by Clang 3.8.0 (tags/RELEASE_380/final 262564))
PASS   : KPtyProcessTest::initTestCase()

   Loc: [/root/kderoot/download/git/kpty/autotests/kptyprocesstest.cpp(219)]

PASS   : KPtyProcessTest::test_suspend_pty()
PASS   : KPtyProcessTest::cleanupTestCase()
Totals: 5 passed, 2 failed, 0 skipped, 0 blacklisted, 2158ms

I dig this out up to KPtyDevicePrivate::_k_canRead() method. When
p.pty()->waitForReadyRead(5000) is called, this function return 0 in available
for ::ioctl(q->masterFd(), PTY_BYTES_AVAILABLE, (char *) &available) call.
This, in turn, leads to readBytes = 0 and method returning false.

I haven't yet figured out what to do with this.
