RDKit not parsing a set of compounds

I am trying to use RDKit to process ChEMBL compounds. However, there is a subset of compounds that get thrown out of the 'fail' port.

 

Examples of such compounds (I am using molfile or smiles and get same result) are:

 

CCCCCCCCCCCC(=O)Oc1ccc(CC[n+]2c(C)cc(C)cc2C)cc1OC(=O)CCCCCCCCCCC.F[P-](F)(F)(F)(F)F

					<table border="0" cellpadding="0" cellspacing="0" style="width:948px">
						<tbody>
							<tr>
								<td style="height:20px; width:948px">
								<p>CN(C)c1ccc2C(=C3C=CC(=[N+](C)C)C=C3[Se]c2c1)c4ccsc4C(=O)O.F[P-](F)(F)(F)(F)F</p>

								<table border="0" cellpadding="0" cellspacing="0" style="width:948px">
									<tbody>
										<tr>
											<td style="height:20px; width:948px">
											<p>CCCCCCC\C=C/CCCCCCCCC(=O)Oc1ccc(CC[n+]2c(C)cc(C)cc2C)cc1OC(=O)CCCCCCCC\C=C/CCCCCCC.F[P-](F)(F)(F)(F)F</p>

											<p>&nbsp;</p>

											<p>Any advice on why RDKit doesn&#39;t like these would be welcomed.</p>

											<p>&nbsp;</p>

											<p>thanks</p>
