#86 new defect

undo after "destroy group" does not recover the group name; ARB crashes after a subsequent try to rename the group

Reported by: meierh Owned by: devel
Priority: major Milestone:
Component: Library (DB) Version: SVN
Keywords: group destroy undo rename Cc:


When I destroy a group (group—>right mouse click on inner tree node; --> destroy), and perform an "undo" errors occurs:

case1: I destroyed group "Bacteria":

  • strange group name (#IGROUP Mrö31) +
  • ARB-Message: ARB is most likely unstable now (due to this error). If you've made changes to the database, consider to save it using a different name. Try to fix the cause of the error and restart ARB. 16:39.28 Internal ARB Error: ARB ERROR: Internal Error: Cannot uncompress data of field


  • Rename Group works

case 2: I destroyed the group Firmicutes

  • ARB-Message: 16:50.19 ARB ERROR: in 'taxonomy(1)': while applying 'taxonomy(1)' to : Group without 'group_name' entry
  • Error Message occurs as group name in the tree: "<error: ARB ERROR: in 'taxonomy(1)': while applying…."
  • ARB crashes with SegFault?, when I try to rename the group

  • similar effect, when group info is moved to a different tree node and then applying undo:
    • group name disappears
    • saving results in unloadable DB (GB_STRING_SHRT-bug; "Unknown DB-type 0"; this bug is already fixed in CVS!)

  • Version changed from stable-2007 to CVS

This effect is not database specific. Occurs too with "SSURef_96_SILVA_04_10_08_opt.arb" and "SSURef_98_SILVA_20_03_09_opt.arb". It occurs just for some groups been destroyed and tried to become restored by pressing the "undo"-button (e.g. for Bacteria, but not for Archaea). 'Group-size-dependant?
