i fixed the schemas in freetds and sybase comparing types and arg cnt, but this did not fix the segfault or produced another one. This is what i found out: Both providers return FALSE for GDA_CONNECTION_FEATURE_SEQUENCES (supports) and NULL for GDA_CONNECTION_SCHEMA_SEQUENCES (get_schema) at the moment. Though mergeant crashes in tableedit.c: update_seq_list_cb(): 534, because te->combobox is NULL. ** Message: MESSAGE: Msg 5701, Level 10, State 1, Server linux2, Line 1 Changed database context to 'master'.

A few traces in 0.8.199, and bug 98670 looks similar. Confirming NEW
I looked a little bit because I ran into it and here is what I found: The crash occurs in update_seq_list_cb when accessing to the combobox used for displaying sequences, but badly this combo have not been created in table_edit_build because wid->conf->srv->features.sequences is false. To avoid crash all access to combobox field should be feature conditional. I tried, as a test to verify, to create the combo when features.sequences is false => the crash vanish. Is my analysis correct ? If this is true I attached a patch for make use of combobox only when seq feature is available
Created attachment 13137 [details] [review] Patch for fixing crash on table props dialog opening
Added a patch to set sequence toolbar shortcut (gnome-db-shortcut) unsensitive when they (sequences) are not available. Not sure it is the right thing to do, nevertheless it let me learn a lot. Hope it will be usefull.
