On Windows, the following code generates an AttributeError, but should probably generate a portNotOpenError instead. The problem seems to be caused by hComPort not being initialized at all, but it should be None.
import serial
ser = serial.Serial(port=None)
ser.write("hello")
Traceback (most recent call last):

If multiple net alises for one net are a problem for the PCB designer or the netlist file format, the schematic designer could be given a dropdown list of aliases for each net, from which they choose the name of the net that should appear in the netlist.

Phil and Don, thanks for the replies.
Don, I am encountering this problem in version 2.70.00 Build #248 Beta.
It sounds like Phil has described the cause of the problem.
On a related note, what is the reason that power symbols are treated differently from normal net labels?.

Net "aliases" are made by putting a net label on a net which already has a "label" or "power label" connected to it. This should just give the net two names, and when generating a netlist, it should appear as one net.
When net aliases are used for power nets (and probably when used for any nets), netlists are not generated correctly. There are missing connections and/or isolated nets. The...

Update:
I looked into the netlist some more. It looks like the netlist is still functional. The proper net connections are made in addition to the hierarchical pins being added as connections.
I haven't verified that all connections are correct in my netlist yet, but it seems that the fix may only be to not add hierarchical symbol pins to the list of pins under a net. For example, if R1...

Nets are not connected correctly into hierarchical in PADS-PCB netlist output. This problem may occur with other outputs as well. I have not checked them.
When creating a hierarchical symbol, pin numbering cannot be set by the user. Instead, it starts at 1 each time the pin button is clicked. This can often result in duplicate pin numberings. This affects netlist output.
In PADS-PCB...

Steps to recreate the bug:
1) Open glade-3.4.3-win32-1\bin\glade-3.exe
2) Click on the "About Dialog" icon in the Toplevels section.
3) Click in the "Authors" text entry box
4) Attempt to enter a character
5) Glade should exit.

I had this problem on ubuntu 8.10. I did the following to fix it, by downgrading to an older version of libtool. You may just be able to run autoreconf -fvi and then it will work. Try that first; if that doesnt work try all of this:
sudo apt-get remove libtool
wget http://ftp.sjtu.edu.cn/ubuntu/pool/main/libt/libtool/libtool_1.5.26-1ubuntu1_i386.deb
sudo dpkg -i...
