LRegionsSelection::addRegion() fails with assertion

LRegionsSelection::addRegion() fails with assertion "assert(r.len > 0);" when user selects annotation in sync'ed multisequence view and the annotation is located outside of other sequence bounds.
The problem resides in ADVSyncViewManager::sl_onSelectionChanged()
...
foreach(LRegion r, added) {
r.startPos -= offset;
if (r.startPos < 0)

{ r.startPos = 0; }

if (r.endPos() > w->getSequenceLen())

{ r.len = w->getSequenceLen() - r.startPos; }

selection->addRegion(r);
}

The cycle above assumes w->getSequenceLen() > r.startPos; which does not hold true when sequences have very different size.
Steps To Reproduce

1) Open 2 following sequences in one view:
trunk\data\samples\Genbank\murine.gb
trunk\test_common_data\edit_sequence\test.gb

2) Press "Lock scales" button on the ADV toolbar

3) Select any CDS feature of the murine.gb
