Eeschema - Assertion failure when editing net labels

[Pekka Harjamäki]

Open pcbnew, click "read netlist" and voila:

ASSERT INFO:
/var/tmp/portage/x11-libs/wxGTK-2.9.4.1/work/wxPython-src-2.9.4.0/src/gtk/textctrl.cpp(846): assert "IsSingleLine()" failed in GetEditable(): shouldn't be called for multiline

Ps. pcb calculator has the same kind of bug left, see: 1167345

Tested with: kicad (BZR 4097), compiled with gcc 4.7.2 on 64-bit system. wxgtk version 2.9.4.1

I see something similar when adding a label in eeschema in bzr 5034. Perhaps these are not related and the eeschema bug should be reported as a separate issue?

This bugs seems to use wxgtk 2.9. Does this mean that it is using wxwidgets 2.9? The minimum version of wx is now 3.0.0.

This bug does not report what versions are used, nor what platform it is running on. Please provide this info. Marking as incomplete.

The assertion when reading the netlist has been fixed since this was reported, but adding or editing net labels in eeschema still causes the assertion reported by Nicklas Björk. I've posted a patch to the mailing list which fixes this -- just waiting for confirmation it doesn't break non-GTK backends and then for somebody to commit it.

[Blair Bonnett (bcb)]

Nick -- GTK added the assertion in 2.9, so this also occurs in 3.

[Blair Bonnett (bcb)]

Patch committed in r5259.

[Nick Østergaard (nickoe)]

 Blair, thank you for fixing.
