[Xlog-discussion] consistent crash?

[Ernest Stracener]

Hello to everyone --

I just recently joined this list and have just compiled xlog 0.7beta5 -- no 
problems with compilation.

While playing around with the various features, I have come upon what seems to 
be an action that causes a consistent crash for me:
1.  Open xlog
2.  Tools --> Log Editor
3.  Rename fields "UNKNOWN" to "test1" and "test2", configure both fields to 
"show"
4.  Exit Log Editor dialog
5.  File --> Save (or Save As w/new filename)
6.  xlog exits abnormally with the following message (full gdb bt output 
appended to this message): 
Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkLabel'
Gtk-CRITICAL **: file gtklabel.c: line 333 (gtk_label_get): assertion `label 
!= NULL' failed.
7.  Opening up xlog again shows unchanged logfile (e.g. test1 & test2 are 
still hidden)

I have also noticed that the labels for the user-defined fields do not appear 
in the log "field-window"...the form fields do show, but not the labels. 

Is this just me or can anyone replicate this crash?

Thought I would pass it along....overall it looks like a great application!  
Can't wait to put it into action!
