Whenever I copy/kill and past a branch inset LyX dies with the error message
../../../src/support/lassert.cpp(21): ASSERTION false VIOLATED IN ../../src/insets/Inset.cpp:137 terminate called after throwing an instance of 'lyx::support::ExceptionMessage' what(): Inset::buffer_ member not initialized! LyX Code: 36 name: Branch in ~/.xsession-errors. I use LyX 1.6.1 on Debian with a set of documents organised as master with childs for each chapter (there are some branch oddities in this setup but this might be unrelated). Is this a known bug that will be fixed in 1.6.2 ?
