Reproducible with Version: 5.4.0.0.alpha1 Build ID: 0b9f9bef65bb21ebb6a64aafad448f7f62dc824a CPU threads: 4; OS: Windows 6.2; UI render: default; Locale: es-ES (es_ES); Calc: single Really not a crash of comment #2, because selecting 'omit' on the error box three times LO goes ahead, so also reproducible with: Version: 5.4.0.0.alpha1+ Build ID: e5a4858e1adf5e9f0c5eb808d2155fded6a46728 CPU threads: 4; OS: Windows 6.19; UI render: GL; TinderBox: Win-x86@39, Branch:master, Time: 2017-05-10_03:50:12 Locale: es-ES (es_ES); Calc: CL
On pc Debian x86-64 with master sources updated today, I could reproduce this. The problem is there may be entries with no parent.
